+# Google Android makefile for curl and libcurl
+#
+# Place the curl source (including this makefile) into external/curl/ in the
+# Android source tree. Then build them with 'make curl' or just 'make libcurl'
+# from the Android root. Tested with Android 1.5
+#
+# Note: you must first create a curl_config.h file by running configure in the
+# Android environment. The only way I've found to do this is tricky. Perform a
+# normal Android build with libcurl in the source tree, providing the target
+# "showcommands" to make. The build will eventually fail (because curl_config.h
+# doesn't exist yet), but the compiler commands used to build curl will be
+# shown. Now, from the external/curl/ directory, run curl's normal configure
+# command with flags that match what Android itself uses. This will mean
+# putting the compiler directory into the PATH, putting the -I, -isystem and
+# -D options into CPPFLAGS, putting the -m, -f, -O and -nostdlib options into
+# CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the path
+# to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o. Remember
+# that the paths must be absolute since you will not be running configure from
+# the same directory as the Android make. The normal cross-compiler options
+# must also be set.
+#
+# The end result will be a configure command that looks something like this
+# (the environment variable A is set to the Android root path):
+#
+# A=`realpath ../..` && \
+# PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \
+# ./configure --host=arm-linux CC=arm-eabi-gcc \
+# CPPFLAGS="-I $A/system/core/include ..." \
+# CFLAGS="-fno-exceptions -Wno-multichar ..." \
+# LIB="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/lib/gcc/arm-eabi/X\

+ Curl is a command line tool for transferring data specified with URL
+ syntax. Find out how to use curl by reading the curl.1 man page or the
+ MANUAL document. Find out how to install Curl by reading the INSTALL
+ document.
+
+ libcurl is the library curl is using to do its job. It is readily
+ available to be used by your software. Read the libcurl.3 man page to
+ learn how!
+
+ You find answers to the most frequent questions we get in the FAQ document.
+
+ Study the COPYING file for distribution terms and similar. If you distribute
+ curl binaries or other binaries that involve libcurl, you might enjoy the
+ LICENSE-MIXING document.
+
+CONTACT
+
+ If you have problems, questions, ideas or suggestions, please contact us
+ by posting to a suitable mailing list. See http://curl.haxx.se/mail/
+
+ All contributors to the project are listed in the THANKS document.

+Include files for libcurl, external users.
+
+They're all placed in the curl subdirectory here for better fit in any kind
+of environment. You must include files from here using...
+
+ #include <curl/curl.h>
+
+... style and point the compiler's include path to the directory holding the
+curl subdirectory. It makes it more likely to survive future modifications.
+
+NOTE FOR LIBCURL HACKERS
+
+The following notes apply to libcurl version 7.19.0 and later.
+
+* The distributed curl/curlbuild.h file is only intended to be used on systems
+ which can not run the also distributed configure script.
+
+* The distributed curlbuild.h file is generated as a copy of curlbuild.h.dist
+ when the libcurl source code distribution archive file is originally created.
+
+* If you check out from git on a non-configure platform, you must run the
+ appropriate buildconf* script to set up curlbuild.h and other local files
+ before being able of compiling the library.
+
+* On systems capable of running the configure script, the configure process
+ will overwrite the distributed include/curl/curlbuild.h file with one that
+ is suitable and specific to the library being configured and built, which
+ is generated from the include/curl/curlbuild.h.in template file.
+
+* If you intend to distribute an already compiled libcurl library you _MUST_
+ also distribute along with it the generated curl/curlbuild.h which has been
+ used to compile it. Otherwise the library will be of no use for the users of
+ the library that you have built. It is _your_ responsability to provide this
+ file. No one at the cURL project can know how you have built the library.
+
+* File curl/curlbuild.h includes platform and configuration dependent info,
+ and must not be modified by anyone. Configure script generates it for you.
+
+* We cannot assume anything else but very basic compiler features being
+ present. While libcurl requires an ANSI C compiler to build, some of the
+ earlier ANSI compilers clearly can't deal with some preprocessor operators.
+
+* Newlines must remain unix-style for older compilers' sake.
+
+* Comments must be written in the old-style /* unnested C-fashion */
+
+To figure out how to do good and portable checks for features, operating
+systems or specific hardwarare, a very good resource is Bjorn Reese's
+collection at http://predef.sf.net/

+/* COMPILE TIME SANITY CHECKS */
+/* ================================================================ */
+
+/*
+ * NOTE 1:
+ * -------
+ *
+ * All checks done in this file are intentionally placed in a public
+ * header file which is pulled by curl/curl.h when an application is
+ * being built using an already built libcurl library. Additionally
+ * this file is also included and used when building the library.
+ *
+ * If compilation fails on this file it is certainly sure that the
+ * problem is elsewhere. It could be a problem in the curlbuild.h
+ * header file, or simply that you are using different compilation
+ * settings than those used to build the library.
+ *
+ * Nothing in this file is intended to be modified or adjusted by the
+ * curl library user nor by the curl library builder.
+ *
+ * Do not deactivate any check, these are done to make sure that the
+ * library is properly built and used.
+ *
+ * You can find further help on the libcurl development mailing list:
+ * http://cool.haxx.se/mailman/listinfo/curl-library/
+ *
+ * NOTE 2
+ * ------
+ *
+ * Some of the following compile time checks are based on the fact
+ * that the dimension of a constant array can not be a negative one.
+ * In this way if the compile time verification fails, the compilation
+ * will fail issuing an error. The error description wording is compiler
+ * dependent but it will be quite similar to one of the following:
+ *
+ * "negative subscript or subscript is too large"
+ * "array must have at least one element"
+ * "-1 is an illegal array size"
+ * "size of array is negative"
+ *
+ * If you are building an application which tries to use an already
+ * built libcurl library and you are getting this kind of errors on
+ * this file, it is a clear indication that there is a mismatch between
+ * how the library was built and how you are trying to use it for your
+ * application. Your already compiled or binary library provider is the
+ * only one who can give you the details you need to properly use it.

+ How To Build libcurl to Use c-ares For Asynch Name Resolves
+ ===========================================================
+
+c-ares:
+ http://c-ares.haxx.se/
+
+NOTE
+ The latest libcurl version requires c-ares 1.4.0 or later.
+
+ Once upon the time libcurl built fine with the "original" ares. That is no
+ longer true. You need to use c-ares.
+
+Build c-ares
+============
+
+1. unpack the c-ares archive
+2. cd c-ares-dir
+3. ./configure
+4. make
+5. make install
+
+Build libcurl to use c-ares in the curl source tree
+===================================================
+
+1. name or symlink the c-ares source directory 'ares' in the curl source
+ directory
+2. ./configure --enable-ares
+
+ Optionally, you can point out the c-ares install tree root with the the
+ --enable-ares option.
+
+3. make
+
+Build libcurl to use an installed c-ares
+========================================
+
+1. ./configure --enable-ares=/path/to/ares/install
+2. make
+
+c-ares on win32
+===============
+(description brought by Dominick Meglio)
+
+First I compiled c-ares. I changed the default C runtime library to be the
+single-threaded rather than the multi-threaded (this seems to be required to
+prevent linking errors later on). Then I simply build the areslib project (the
+other projects adig/ahost seem to fail under MSVC).
+
+Next was libcurl. I opened lib/config-win32.h and I added a:
+ #define USE_ARES 1
+
+Next thing I did was I added the path for the ares includes to the include
+path, and the libares.lib to the libraries.
+
+Lastly, I also changed libcurl to be single-threaded rather than
+multi-threaded, again this was to prevent some duplicate symbol errors. I'm
+not sure why I needed to change everything to single-threaded, but when I
+didn't I got redefinition errors for several CRT functions (malloc, stricmp,
+etc.)
+
+I would have modified the MSVC++ project files, but I only have VC.NET and it
+uses a different format than VC6.0 so I didn't want to go and change
+everything and remove VC6.0 support from libcurl.

+
+ curl_off_t explained
+ ====================
+
+curl_off_t is a data type provided by the external libcurl include headers. It
+is the type meant to be used for the curl_easy_setopt() options that end with
+LARGE. The type is 64bit large on most modern platforms.
+
+Transition from < 7.19.0 to >= 7.19.0
+-------------------------------------
+
+Applications that used libcurl before 7.19.0 that are rebuilt with a libcurl
+that is 7.19.0 or later may or may not have to worry about anything of
+this. We have made a significant effort to make the transition really seamless
+and transparent.
+
+You have have to take notice if you are in one of the following situations:
+
+o Your app is using or will after the transition use a libcurl that is built
+ with LFS (large file support) disabled even though your system otherwise
+ supports it.
+
+o Your app is using or will after the transition use a libcurl that doesn't
+ support LFS at all, but your system and compiler support 64bit data types.
+
+In both these cases, the curl_off_t type will now (after the transition) be
+64bit where it previously was 32bit. This will cause a binary incompatibility
+that you MAY need to deal with.
+
+Benefits
+--------
+
+This new way has several benefits:
+
+o Platforms without LFS support can still use libcurl to do >32 bit file
+ transfers and range operations etc as long as they have >32 bit data-types
+ supported.
+
+o Applications will no longer easily build with the curl_off_t size
+ mismatched, which has been a very frequent (and annoying) problem with
+ libcurl <= 7.18.2
+
+Historically
+------------
+
+Previously, before 7.19.0, the curl_off_t type would be rather strongly
+connected to the size of the system off_t type, where currently curl_off_t is
+independent of that.
+
+The strong connection to off_t made it troublesome for application authors
+since when they did mistakes, they could get curl_off_t type of different
+sizes in the app vs libcurl, and that caused strange effects that were hard to
+track and detect by users of libcurl.
+
+SONAME
+------
+
+We opted to not bump the soname for the library unconditionally, simply
+because soname bumping is causing a lot of grief and moaning all over the
+community so we try to keep that at minimum. Also, our selected design path
+should be 100% backwards compatible for the vast majority of all libcurl
+users.
+
+Enforce SONAME bump
+-------------------
+
+If configure doesn't detect your case where a bump is necessary, re-run it
+with the --enable-soname-bump command line option!

+ Source Code Functions Apps Might Use
+ ====================================
+
+The libcurl source code offers a few functions by source only. They are not
+part of the official libcurl API, but the source files might be useful for
+others so apps can optionally compile/build with these sources to gain
+additional functions.
+
+We provide them through a single header file for easy access for apps:
+"curlx.h"
+
+ curlx_strtoofft()
+
+ A macro that converts a string containing a number to a curl_off_t number.
+ This might use the curlx_strtoll() function which is provided as source
+ code in strtoofft.c. Note that the function is only provided if no
+ strtoll() (or equivalent) function exist on your platform. If curl_off_t
+ is only a 32 bit number on your platform, this macro uses strtol().
+
+ curlx_tvnow()
+
+ returns a struct timeval for the current time.
+
+ curlx_tvdiff()
+
+ returns the difference between two timeval structs, in number of
+ milliseconds.
+
+ curlx_tvdiff_secs()
+
+ returns the same as curlx_tvdiff but with full usec resolution (as a
+ double)
+
+FUTURE
+======
+
+ Several functions will be removed from the public curl_ name space in a
+ future libcurl release. They will then only become available as curlx_
+ functions instead. To make the transition easier, we already today provide
+ these functions with the curlx_ prefix to allow sources to get built properly
+ with the new function names. The functions this concerns are:
+
+ curlx_getenv
+ curlx_strequal
+ curlx_strnequal
+ curlx_mvsnprintf
+ curlx_msnprintf
+ curlx_maprintf
+ curlx_mvaprintf
+ curlx_msprintf
+ curlx_mprintf
+ curlx_mfprintf
+ curlx_mvsprintf
+ curlx_mvprintf
+ curlx_mvfprintf

+
+ Content Encoding Support for libcurl
+
+* About content encodings:
+
+HTTP/1.1 [RFC 2616] specifies that a client may request that a server encode
+its response. This is usually used to compress a response using one of a set
+of commonly available compression techniques. These schemes are `deflate' (the
+zlib algorithm), `gzip' and `compress' [sec 3.5, RFC 2616]. A client requests
+that the sever perform an encoding by including an Accept-Encoding header in
+the request document. The value of the header should be one of the recognized
+tokens `deflate', ... (there's a way to register new schemes/tokens, see sec
+3.5 of the spec). A server MAY honor the client's encoding request. When a
+response is encoded, the server includes a Content-Encoding header in the
+response. The value of the Content-Encoding header indicates which scheme was
+used to encode the data.
+
+A client may tell a server that it can understand several different encoding
+schemes. In this case the server may choose any one of those and use it to
+encode the response (indicating which one using the Content-Encoding header).
+It's also possible for a client to attach priorities to different schemes so
+that the server knows which it prefers. See sec 14.3 of RFC 2616 for more
+information on the Accept-Encoding header.
+
+* Current support for content encoding:
+
+Support for the 'deflate' and 'gzip' content encoding are supported by
+libcurl. Both regular and chunked transfers should work fine. The library
+zlib is required for this feature. 'deflate' support was added by James
+Gallagher, and support for the 'gzip' encoding was added by Dan Fandrich.
+
+* The libcurl interface:
+
+To cause libcurl to request a content encoding use:
+
+ curl_easy_setopt(curl, CURLOPT_ENCODING, <string>)
+
+where <string> is the intended value of the Accept-Encoding header.
+
+Currently, libcurl only understands how to process responses that use the
+"deflate" or "gzip" Content-Encoding, so the only values for CURLOPT_ENCODING
+that will work (besides "identity," which does nothing) are "deflate" and
+"gzip" If a response is encoded using the "compress" or methods, libcurl will
+return an error indicating that the response could not be decoded. If
+<string> is NULL no Accept-Encoding header is generated. If <string> is a
+zero-length string, then an Accept-Encoding header containing all supported
+encodings will be generated.
+
+The CURLOPT_ENCODING must be set to any non-NULL value for content to be
+automatically decoded. If it is not set and the server still sends encoded
+content (despite not having been asked), the data is returned in its raw form
+and the Content-Encoding type is not checked.
+
+* The curl interface:
+
+Use the --compressed option with curl to cause it to ask servers to compress
+responses using any format supported by curl.

+ hostip.c explained
+ ==================
+
+ The main COMPILE-TIME DEFINES to keep in mind when reading the host*.c
+ source file are these:
+
+ CURLRES_IPV6 - this host has getaddrinfo() and family, and thus we use
+ that. The host may not be able to resolve IPv6, but we don't really have to
+ take that into account. Hosts that aren't IPv6-enabled have CURLRES_IPV4
+ defined.
+
+ CURLRES_ARES - is defined if libcurl is built to use c-ares for asynchronous
+ name resolves. It cannot have ENABLE_IPV6 defined at the same time, as c-ares
+ has no ipv6 support. This can be Windows or *nix.
+
+ CURLRES_THREADED - is defined if libcurl is built to run under (native)
+ Windows, and then the name resolve will be done in a new thread, and the
+ supported asynch API will be the same as for ares-builds.
+
+ If any of the two previous are defined, CURLRES_ASYNCH is defined too. If
+ libcurl is not built to use an asynchronous resolver, CURLRES_SYNCH is
+ defined.
+
+ The host*.c sources files are split up like this:
+
+ hostip.c - method-independent resolver functions and utility functions
+ hostasyn.c - functions for asynchronous name resolves
+ hostsyn.c - functions for synchronous name resolves
+ hostares.c - functions for ares-using name resolves
+ hostthre.c - functions for threaded name resolves
+ hostip4.c - ipv4-specific functions
+ hostip6.c - ipv6-specific functions
+
+ The hostip.h is the single united header file for all this. It defines the
+ CURLRES_* defines based on the config*.h and setup.h defines.

+1. PUT/POST without a known auth to use (possibly no auth required):
+
+ (When explicitly set to use a multi-pass auth when doing a POST/PUT,
+ libcurl should immediately go the Content-Length: 0 bytes route to avoid
+ the first send all data phase, step 2. If told to use a single-pass auth,
+ goto step 3.)
+
+ Issue the proper PUT/POST request immediately, with the correct
+ Content-Length and Expect: headers.
+
+ If a 100 response is received or the wait for one times out, start sending
+ the request-body.
+
+ If a 401 (or 407 when talking through a proxy) is received, then:
+
+ If we have "more than just a little" data left to send, close the
+ connection. Exactly what "more than just a little" means will have to be
+ determined. Possibly the current transfer speed should be taken into
+ account as well.
+
+ NOTE: if the size of the POST data is less than MAX_INITIAL_POST_SIZE (when
+ CURLOPT_POSTFIELDS is used), libcurl will send everything in one single
+ write() (all request-headers and request-body) and thus it will
+ unconditionally send the full post data here.
+
+2. PUT/POST with multi-pass auth but not yet completely negotiated:
+
+ Send a PUT/POST request, we know that it will be rejected and thus we claim
+ Content-Length zero to avoid having to send the request-body. (This seems
+ to be what IE does.)
+
+3. PUT/POST as the last step in the auth negotiation, that is when we have
+ what we believe is a completed negotiation:
+
+ Send a full and proper PUT/POST request (again) with the proper
+ Content-Length and a following request-body.
+
+ NOTE: this may very well be the second (or even third) time the whole or at
+ least parts of the request body is sent to the server. Since the data may
+ be provided to libcurl with a callback, we need a way to tell the app that
+ the upload is to be restarted so that the callback will provide data from
+ the start again. This requires an API method/mechanism that libcurl
+ doesn't have today. See below.
+
+Data Rewind
+
+ It will be troublesome for some apps to deal with a rewind like this in all
+ circumstances. I'm thinking for example when using 'curl' to upload data
+ from stdin. If libcurl ends up having to rewind the reading for a request
+ to succeed, of course a lack of this callback or if it returns failure, will
+ cause the request to fail completely.
+
+ The new callback is set with CURLOPT_IOCTLFUNCTION (in an attempt to add a
+ more generic function that might be used for other IO-related controls in
+ the future):
+
+ curlioerr curl_ioctl(CURL *handle, curliocmd cmd, void *clientp);
+
+ And in the case where the read is to be rewinded, it would be called with a
+ cmd named CURLIOCMD_RESTARTREAD. The callback would then return CURLIOE_OK,
+ if things are fine, or CURLIOE_FAILRESTART if not.
+
+Backwards Compatibility
+
+ The approach used until now, that issues a HEAD on the given URL to trigger
+ the auth negotiation could still be supported and encouraged, but it would
+ be up to the app to first fetch a URL with GET/HEAD to negotiate on, since
+ then a following PUT/POST wouldn't need to negotiate authentication and
+ thus avoid double-sending data.
+
+ Optionally, we keep the current approach if some option is set
+ (CURLOPT_HEADBEFOREAUTH or similar), since it seems to work fairly well for
+ POST on most servers.

+ How To Track Down Suspected Memory Leaks in libcurl
+ ===================================================
+
+Single-threaded
+
+ Please note that this memory leak system is not adjusted to work in more
+ than one thread. If you want/need to use it in a multi-threaded app. Please
+ adjust accordingly.
+
+
+Build
+
+ Rebuild libcurl with -DCURLDEBUG (usually, rerunning configure with
+ --enable-debug fixes this). 'make clean' first, then 'make' so that all
+ files actually are rebuilt properly. It will also make sense to build
+ libcurl with the debug option (usually -g to the compiler) so that debugging
+ it will be easier if you actually do find a leak in the library.
+
+ This will create a library that has memory debugging enabled.
+
+Modify Your Application
+
+ Add a line in your application code:
+
+ curl_memdebug("dump");
+
+ This will make the malloc debug system output a full trace of all resource
+ using functions to the given file name. Make sure you rebuild your program
+ and that you link with the same libcurl you built for this purpose as
+ described above.
+
+Run Your Application
+
+ Run your program as usual. Watch the specified memory trace file grow.
+
+ Make your program exit and use the proper libcurl cleanup functions etc. So
+ that all non-leaks are returned/freed properly.
+
+Analyze the Flow
+
+ Use the tests/memanalyze.pl perl script to analyze the dump file:
+
+ tests/memanalyze.pl dump
+
+ This now outputs a report on what resources that were allocated but never
+ freed etc. This report is very fine for posting to the list!
+
+ If this doesn't produce any output, no leak was detected in libcurl. Then
+ the leak is mostly likely to be in your code.

+Implementation of the curl_multi_socket API
+
+ The main ideas of the new API are simply:
+
+ 1 - The application can use whatever event system it likes as it gets info
+ from libcurl about what file descriptors libcurl waits for what action
+ on. (The previous API returns fd_sets which is very select()-centric).
+
+ 2 - When the application discovers action on a single socket, it calls
+ libcurl and informs that there was action on this particular socket and
+ libcurl can then act on that socket/transfer only and not care about
+ any other transfers. (The previous API always had to scan through all
+ the existing transfers.)
+
+ The idea is that curl_multi_socket_action() calls a given callback with
+ information about what socket to wait for what action on, and the callback
+ only gets called if the status of that socket has changed.
+
+ We also added a timer callback that makes libcurl call the application when
+ the timeout value changes, and you set that with curl_multi_setopt() and the
+ CURLMOPT_TIMERFUNCTION option. To get this to work, Internally, there's an
+ added a struct to each easy handle in which we store an "expire time" (if
+ any). The structs are then "splay sorted" so that we can add and remove
+ times from the linked list and yet somewhat swiftly figure out both how long
+ time there is until the next nearest timer expires and which timer (handle)
+ we should take care of now. Of course, the upside of all this is that we get
+ a curl_multi_timeout() that should also work with old-style applications
+ that use curl_multi_perform().
+
+ We created an internal "socket to easy handles" hash table that given
+ a socket (file descriptor) return the easy handle that waits for action on
+ that socket. This hash is made using the already existing hash code
+ (previously only used for the DNS cache).
+
+ To make libcurl able to report plain sockets in the socket callback, we had
+ to re-organize the internals of the curl_multi_fdset() etc so that the
+ conversion from sockets to fd_sets for that function is only done in the
+ last step before the data is returned. I also had to extend c-ares to get a
+ function that can return plain sockets, as that library too returned only
+ fd_sets and that is no longer good enough. The changes done to c-ares are
+ available in c-ares 1.3.1 and later.
+
+ We have done a test runs with up to 9000 connections (with a single active
+ one). The curl_multi_socket_action() invoke then takes less than 10
+ microseconds in average (using the read-only-1-byte-at-a-time hack). We are
+ now below the 60 microseconds "per socket action" goal (the extra 50 is the
+ time libevent needs).

+Pingpong
+========

+ Pingpong is just my (Daniel's) jestful collective name on the protocols that
+ share a very similar kind of back-and-forth procedure with command and

+
+FTP
+
+ In 7.20.0 we converted code to use the new pingpong code from previously

+
+ There's no official URL syntax defined for SMTP, but we use only the generic
+ one and we provide two additional libcurl options to specify receivers and

+HTTP Pipelining with libcurl
+============================
+
+Background
+
+Since pipelining implies that one or more requests are sent to a server before
+the previous response(s) have been received, we only support it for multi
+interface use.
+
+Considerations
+
+When using the multi interface, you create one easy handle for each transfer.
+Bascially any number of handles can be created, added and used with the multi
+interface - simultaneously. It is an interface designed to allow many
+simultaneous transfers while still using a single thread. Pipelining does not
+change any of these details.
+
+API
+
+We've added a new option to curl_multi_setopt() called CURLMOPT_PIPELINING
+that enables "attempted pipelining" and then all easy handles used on that
+handle will attempt to use an existing pipeline.
+
+Details
+
+- A pipeline is only created if a previous connection exists to the same IP
+ address that the new request is being made to use.
+
+- Pipelines are only supported for HTTP(S) as no other currently supported
+ protocol has features resemembling this, but we still name this feature
+ plain 'pipelining' to possibly one day support it for other protocols as
+ well.
+
+- HTTP Pipelining is for GET and HEAD requests only.
+
+- When a pipeline is in use, we must take precautions so that when used easy
+ handles (i.e those who still wait for a response) are removed from the multi
+ handle, we must deal with the outstanding response nicely.
+
+- Explicitly asking for pipelining handle X and handle Y won't be supported.
+ It isn't easy for an app to do this association. The lib should probably
+ still resolve the second one properly to make sure that they actually _can_
+ be considered for pipelining. Also, asking for explicit pipelining on handle
+ X may be tricky when handle X get a closed connection.
+
+- We need options to control max pipeline length, and probably how to behave
+ if we reach that limit. As was discussed on the list, it can probably be
+ made very complicated, so perhaps we can think of a way to pass all
+ variables involved to a callback and let the application decide how to act
+ in specific situations. Either way, these fancy options are only interesting
+ to work on when everything is working and we have working apps to test with.

+RECEIVING COOKIE INFORMATION
+============================
+
+struct CookieInfo *cookie_init(char *file);
+
+ Inits a cookie struct to store data in a local file. This is always
+ called before any cookies are set.
+
+int cookies_set(struct CookieInfo *cookie, char *cookie_line);
+
+ The 'cookie_line' parameter is a full "Set-cookie:" line as
+ received from a server.
+
+ The function need to replace previously stored lines that this new
+ line superceeds.
+
+ It may remove lines that are expired.
+
+ It should return an indication of success/error.
+
+
+SENDING COOKIE INFORMATION
+==========================
+
+struct Cookies *cookie_getlist(struct CookieInfo *cookie,
+ char *host, char *path, bool secure);
+
+ For a given host and path, return a linked list of cookies that
+ the client should send to the server if used now. The secure
+ boolean informs the cookie if a secure connection is achieved or
+ not.
+
+ It shall only return cookies that haven't expired.
+
+
+Example set of cookies:
+
+ Set-cookie: PRODUCTINFO=webxpress; domain=.fidelity.com; path=/; secure
+ Set-cookie: PERSONALIZE=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;

+ * FormAdd()

+ * content is stored.
+ *
+ * While you may have only one byte array for each name, multiple filenames
+ * are allowed (and because of this feature CURLFORM_END is needed after
+ * using CURLFORM_FILE).
+ *
+ * Examples:
+ *
+ * Simple name/value pair with copied contents:
+ * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
+ * CURLFORM_COPYCONTENTS, "value", CURLFORM_END);
+ *
+ * name/value pair where only the content pointer is remembered:
+ * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
+ * CURLFORM_PTRCONTENTS, ptr, CURLFORM_CONTENTSLENGTH, 10, CURLFORM_END);
+ * (if CURLFORM_CONTENTSLENGTH is missing strlen () is used)
+ *
+ * storing a filename (CONTENTTYPE is optional!):
+ * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
+ * CURLFORM_FILE, "filename1", CURLFORM_CONTENTTYPE, "plain/text",
+ * CURLFORM_END);
+ *
+ * storing multiple filenames:
+ * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
+ * CURLFORM_FILE, "filename1", CURLFORM_FILE, "filename2", CURLFORM_END);
+ *
+ * Returns:
+ * CURL_FORMADD_OK on success
+ * CURL_FORMADD_MEMORY if the FormInfo allocation fails
+ * CURL_FORMADD_OPTION_TWICE if one option is given twice for one Form
+ * CURL_FORMADD_NULL if a null pointer was given for a char
+ * CURL_FORMADD_MEMORY if the allocation of a FormInfo struct failed
+ * CURL_FORMADD_UNKNOWN_OPTION if an unknown option was used
+ * CURL_FORMADD_INCOMPLETE if the some FormInfo is not complete (or an error)
+ * CURL_FORMADD_MEMORY if a HttpPost struct cannot be allocated
+ * CURL_FORMADD_MEMORY if some allocation for string copying failed.

+ *
+ * CURLRES_IPV6 - this host has getaddrinfo() and family, and thus we use
+ * that. The host may not be able to resolve IPv6, but we don't really have to
+ * take that into account. Hosts that aren't IPv6-enabled have CURLRES_IPV4
+ * defined.
+ *
+ * CURLRES_ARES - is defined if libcurl is built to use c-ares for
+ * asynchronous name resolves. This can be Windows or *nix.
+ *
+ * CURLRES_THREADED - is defined if libcurl is built to run under (native)
+ * Windows, and then the name resolve will be done in a new thread, and the
+ * supported API will be the same as for ares-builds.
+ *
+ * If any of the two previous are defined, CURLRES_ASYNCH is defined too. If
+ * libcurl is not built to use an asynchronous resolver, CURLRES_SYNCH is
+ * defined.
+ *
+ * The host*.c sources files are split up like this:
+ *
+ * hostip.c - method-independent resolver functions and utility functions
+ * hostasyn.c - functions for asynchronous name resolves
+ * hostsyn.c - functions for synchronous name resolves
+ * hostares.c - functions for ares-using name resolves
+ * hostthre.c - functions for threaded name resolves
+ * hostip4.c - ipv4-specific functions
+ * hostip6.c - ipv6-specific functions
+ *
+ * The hostip.h is the united header file for all this. It defines the
+ * CURLRES_* defines based on the config*.h and setup.h defines.

+ * limiting. It simply has a fixed-size array, and on each entry in the array
+ * it has a linked list with entries. So the hash only checks which list to
+ * scan through. The code I had used so for used a list with merely 7 slots
+ * (as that is what the DNS hash uses) but with 7000 connections that would
+ * make an average of 1000 nodes in each list to run through. I upped that to
+ * 97 slots (I believe a prime is suitable) and noticed a significant speed
+ * increase. I need to reconsider the hash implementation or use a rather
+ * large default value like this. At 9000 connections I was still below 10us

+"NAME\n"
+" curl - transfer a URL\n"
+"\n"
+"SYNOPSIS\n"
+" curl [options] [URL...]\n"
+"\n"
+"DESCRIPTION\n"
+" curl is a tool to transfer data from or to a server, using one of the\n"
+" supported protocols (HTTP, HTTPS, FTP, FTPS, SCP, SFTP, TFTP, DICT,\n"
+, stdout);
+ fputs(
+" TELNET, LDAP or FILE). The command is designed to work without user\n"
+" interaction.\n"
+"\n"
+" curl offers a busload of useful tricks like proxy support, user authen-\n"
+" tication, FTP upload, HTTP post, SSL connections, cookies, file trans-\n"
+" fer resume and more. As you will see below, the number of features will\n"
+" make your head spin!\n"
+"\n"
+" curl is powered by libcurl for all transfer-related features. See\n"
+" libcurl(3) for details.\n"
+"\n"
+"URL\n"
+, stdout);
+ fputs(
+" The URL syntax is protocol-dependent. You'll find a detailed descrip-\n"
+" tion in RFC 3986.\n"
+"\n"
+" You can specify multiple URLs or parts of URLs by writing part sets\n"
+" within braces as in:\n"
+"\n"
+" http://site.{one,two,three}.com\n"
+"\n"
+" or you can get sequences of alphanumeric series by using [] as in:\n"
+"\n"
+" ftp://ftp.numericals.com/file[1-100].txt\n"
+" ftp://ftp.numericals.com/file[001-100].txt (with leading zeros)\n"
+" ftp://ftp.letters.com/file[a-z].txt\n"
+"\n"
+, stdout);
+ fputs(
+" No nesting of the sequences is supported at the moment, but you can use\n"
+" several ones next to each other:\n"
+"\n"
+" http://any.org/archive[1996-1999]/vol[1-4]/part{a,b,c}.html\n"
+"\n"
+" You can specify any amount of URLs on the command line. They will be\n"
+" fetched in a sequential manner in the specified order.\n"
+"\n"
+" Since curl 7.15.1 you can also specify a step counter for the ranges,\n"
+" so that you can get every Nth number or letter:\n"
+"\n"
+, stdout);
+ fputs(
+" http://www.numericals.com/file[1-100:10].txt\n"
+" http://www.letters.com/file[a-z:2].txt\n"
+"\n"
+" If you specify URL without protocol:// prefix, curl will attempt to\n"
+" guess what protocol you might want. It will then default to HTTP but\n"
+" try other protocols based on often-used host name prefixes. For exam-\n"
+" ple, for host names starting with \"ftp.\" curl will assume you want to\n"
+" speak FTP.\n"
+"\n"
+, stdout);
+ fputs(
+" curl will do its best to use what you pass to it as a URL. It is not\n"
+" trying to validate it as a syntactically correct URL by any means but\n"
+" is instead very liberal with what it accepts.\n"
+"\n"
+" Curl will attempt to re-use connections for multiple file transfers, so\n"
+" that getting many files from the same server will not do multiple con-\n"
+" nects / handshakes. This improves speed. Of course this is only done on\n"
+, stdout);
+ fputs(
+" files specified on a single command line and cannot be used between\n"
+" separate curl invokes.\n"
+"\n"
+"PROGRESS METER\n"
+" curl normally displays a progress meter during operations, indicating\n"
+" the amount of transferred data, transfer speeds and estimated time\n"
+" left, etc.\n"
+"\n"
+" However, since curl displays this data to the terminal by default, if\n"
+" you invoke curl to do an operation and it is about to write data to the\n"
+, stdout);
+ fputs(
+" terminal, it disables the progress meter as otherwise it would mess up\n"
+" the output mixing progress meter and response data.\n"
+"\n"
+" If you want a progress meter for HTTP POST or PUT requests, you need to\n"
+" redirect the response output to a file, using shell redirect (>), -o\n"
+" [file] or similar.\n"
+"\n"
+" It is not the same case for FTP upload as that operation does not spit\n"
+" out any response data to the terminal.\n"
+"\n"
+, stdout);
+ fputs(
+" If you prefer a progress \"bar\" instead of the regular meter, -# is your\n"
+" friend.\n"
+"OPTIONS\n"
+" In general, all boolean options are enabled with --option and yet again\n"
+" disabled with --no-option. That is, you use the exact same option name\n"
+" but prefix it with \"no-\". However, in this list we mostly only list and\n"
+" show the --option version of them. (This concept with --no options was\n"
+" added in 7.19.0. Previously most options were toggled on/off on\n"
+, stdout);
+ fputs(
+" repeated use of the same command line option.)\n"
+"\n"
+" -a/--append\n"
+" (FTP/SFTP) When used in an upload, this will tell curl to append\n"
+" to the target file instead of overwriting it. If the file\n"
+" doesn't exist, it will be created. Note that this flag is\n"
+" ignored by some SSH servers (including OpenSSH).\n"
+"\n"
+" -A/--user-agent <agent string>\n"
+" (HTTP) Specify the User-Agent string to send to the HTTP server.\n"
+, stdout);
+ fputs(
+" Some badly done CGIs fail if this field isn't set to\n"
+" \"Mozilla/4.0\". To encode blanks in the string, surround the\n"
+" string with single quote marks. This can also be set with the\n"
+" -H/--header option of course.\n"
+"\n"
+" If this option is set more than once, the last one will be the\n"
+" one that's used.\n"
+"\n"
+" --anyauth\n"
+" (HTTP) Tells curl to figure out authentication method by itself,\n"
+, stdout);
+ fputs(
+" and use the most secure one the remote site claims to support.\n"
+" This is done by first doing a request and checking the response-\n"
+" headers, thus possibly inducing an extra network round-trip.\n"
+" This is used instead of setting a specific authentication\n"
+" method, which you can do with --basic, --digest, --ntlm, and\n"
+" --negotiate.\n"
+"\n"
+, stdout);
+ fputs(
+" Note that using --anyauth is not recommended if you do uploads\n"
+" from stdin, since it may require data to be sent twice and then\n"
+" the client must be able to rewind. If the need should arise when\n"
+" uploading from stdin, the upload operation will fail.\n"
+"\n"
+" -b/--cookie <name=data>\n"
+" (HTTP) Pass the data to the HTTP server as a cookie. It is sup-\n"
+" posedly the data previously received from the server in a \"Set-\n"
+, stdout);
+ fputs(
+" Cookie:\" line. The data should be in the format \"NAME1=VALUE1;\n"
+" NAME2=VALUE2\".\n"
+"\n"
+" If no '=' symbol is used in the line, it is treated as a file-\n"
+" name to use to read previously stored cookie lines from, which\n"
+" should be used in this session if they match. Using this method\n"
+" also activates the \"cookie parser\" which will make curl record\n"
+, stdout);
+ fputs(
+" incoming cookies too, which may be handy if you're using this in\n"
+" combination with the -L/--location option. The file format of\n"
+" the file to read cookies from should be plain HTTP headers or\n"
+" the Netscape/Mozilla cookie file format.\n"
+"\n"
+" NOTE that the file specified with -b/--cookie is only used as\n"
+" input. No cookies will be stored in the file. To store cookies,\n"
+, stdout);
+ fputs(
+" use the -c/--cookie-jar option or you could even save the HTTP\n"
+" headers to a file using -D/--dump-header!\n"
+"\n"
+" If this option is set more than once, the last one will be the\n"
+" one that's used.\n"
+"\n"
+" -B/--use-ascii\n"
+" Enable ASCII transfer when using FTP or LDAP. For FTP, this can\n"
+" also be enforced by using an URL that ends with \";type=A\". This\n"
+, stdout);
+ fputs(
+" option causes data sent to stdout to be in text mode for win32\n"
+" systems.\n"
+"\n"
+" --basic\n"
+" (HTTP) Tells curl to use HTTP Basic authentication. This is the\n"
+" default and this option is usually pointless, unless you use it\n"
+" to override a previously set option that sets a different\n"
+" authentication method (such as --ntlm, --digest, or --negoti-\n"
+" ate).\n"
+"\n"
+" --ciphers <list of ciphers>\n"
+, stdout);
+ fputs(
+" (SSL) Specifies which ciphers to use in the connection. The list\n"
+" of ciphers must specify valid ciphers. Read up on SSL cipher\n"
+" list details on this URL:\n"
+" http://www.openssl.org/docs/apps/ciphers.html\n"
+"\n"
+" NSS ciphers are done differently than OpenSSL and GnuTLS. The\n"
+" full list of NSS ciphers is in the NSSCipherSuite entry at this\n"
+, stdout);
+ fputs(
+" URL: http://directory.fedora.redhat.com/docs/mod_nss.html#Direc-\n"
+" tives\n"
+"\n"
+" If this option is used several times, the last one will override\n"
+" the others.\n"
+"\n"
+" --compressed\n"
+" (HTTP) Request a compressed response using one of the algorithms\n"
+" libcurl supports, and return the uncompressed document. If this\n"
+" option is used and the server sends an unsupported encoding,\n"
+, stdout);
+ fputs(
+" curl will report an error.\n"
+"\n"
+" --connect-timeout <seconds>\n"
+" Maximum time in seconds that you allow the connection to the\n"
+" server to take. This only limits the connection phase, once\n"
+" curl has connected this option is of no more use. See also the\n"
+" -m/--max-time option.\n"
+"\n"
+" If this option is used several times, the last one will be used.\n"
+"\n"
+" -c/--cookie-jar <file name>\n"
+, stdout);
+ fputs(
+" Specify to which file you want curl to write all cookies after a\n"
+" completed operation. Curl writes all cookies previously read\n"
+" from a specified file as well as all cookies received from\n"
+" remote server(s). If no cookies are known, no file will be writ-\n"
+" ten. The file will be written using the Netscape cookie file\n"
+" format. If you set the file name to a single dash, \"-\", the\n"
+, stdout);
+ fputs(
+" cookies will be written to stdout.\n"
+"\n"
+" NOTE If the cookie jar can't be created or written to, the whole\n"
+" curl operation won't fail or even report an error clearly. Using\n"
+" -v will get a warning displayed, but that is the only visible\n"
+" feedback you get about this possibly lethal situation.\n"
+"\n"
+" If this option is used several times, the last specified file\n"
+" name will be used.\n"
+"\n"
+, stdout);
+ fputs(
+" -C/--continue-at <offset>\n"
+" Continue/Resume a previous file transfer at the given offset.\n"
+" The given offset is the exact number of bytes that will be\n"
+" skipped, counting from the beginning of the source file before\n"
+" it is transferred to the destination. If used with uploads, the\n"
+" FTP server command SIZE will not be used by curl.\n"
+"\n"
+" Use \"-C -\" to tell curl to automatically find out where/how to\n"
+, stdout);
+ fputs(
+" resume the transfer. It then uses the given output/input files\n"
+" to figure that out.\n"
+"\n"
+" If this option is used several times, the last one will be used.\n"
+"\n"
+" --create-dirs\n"
+" When used in conjunction with the -o option, curl will create\n"
+" the necessary local directory hierarchy as needed. This option\n"
+" creates the dirs mentioned with the -o option, nothing else. If\n"
+, stdout);
+ fputs(
+" the -o file name uses no dir or if the dirs it mentions already\n"
+" exist, no dir will be created.\n"
+"\n"
+" To create remote directories when using FTP or SFTP, try --ftp-\n"
+" create-dirs.\n"
+"\n"
+" --crlf (FTP) Convert LF to CRLF in upload. Useful for MVS (OS/390).\n"
+"\n"
+" --crlfile <file>\n"
+" (HTTPS/FTPS) Provide a file using PEM format with a Certificate\n"
+" Revocation List that may specify peer certificates that are to\n"
+, stdout);
+ fputs(
+" be considered revoked.\n"
+"\n"
+" If this option is used several times, the last one will be used.\n"
+"\n"
+" (Added in 7.19.7)\n"
+"\n"
+" -d/--data <data>\n"
+" (HTTP) Sends the specified data in a POST request to the HTTP\n"
+" server, in the same way that a browser does when a user has\n"
+" filled in an HTML form and presses the submit button. This will\n"
+" cause curl to pass the data to the server using the content-type\n"
+, stdout);
+ fputs(
+" application/x-www-form-urlencoded. Compare to -F/--form.\n"
+"\n"
+" -d/--data is the same as --data-ascii. To post data purely\n"
+" binary, you should instead use the --data-binary option. To URL-\n"
+" encode the value of a form field you may use --data-urlencode.\n"
+"\n"
+" If any of these options is used more than once on the same com-\n"
+" mand line, the data pieces specified will be merged together\n"
+, stdout);
+ fputs(
+" with a separating &-symbol. Thus, using '-d name=daniel -d\n"
+" skill=lousy' would generate a post chunk that looks like\n"
+" 'name=daniel&skill=lousy'.\n"
+"\n"
+" If you start the data with the letter @, the rest should be a\n"
+" file name to read the data from, or - if you want curl to read\n"
+" the data from stdin. The contents of the file must already be\n"
+, stdout);
+ fputs(
+" URL-encoded. Multiple files can also be specified. Posting data\n"
+" from a file named 'foobar' would thus be done with --data @foo-\n"
+" bar.\n"
+"\n"
+" --data-binary <data>\n"
+" (HTTP) This posts data exactly as specified with no extra pro-\n"
+" cessing whatsoever.\n"
+"\n"
+" If you start the data with the letter @, the rest should be a\n"
+" filename. Data is posted in a similar manner as --data-ascii\n"
+, stdout);
+ fputs(
+" does, except that newlines are preserved and conversions are\n"
+" never done.\n"
+"\n"
+" If this option is used several times, the ones following the\n"
+" first will append data as described in -d/--data.\n"
+"\n"
+" --data-urlencode <data>\n"
+" (HTTP) This posts data, similar to the other --data options with\n"
+" the exception that this performs URL-encoding. (Added in 7.18.0)\n"
+, stdout);
+ fputs(
+" To be CGI-compliant, the <data> part should begin with a name\n"
+" followed by a separator and a content specification. The <data>\n"
+" part can be passed to curl using one of the following syntaxes:\n"
+"\n"
+" content\n"
+" This will make curl URL-encode the content and pass that\n"
+" on. Just be careful so that the content doesn't contain\n"
+" any = or @ symbols, as that will then make the syntax\n"

+" =content\n"
+" This will make curl URL-encode the content and pass that\n"
+" on. The preceding = symbol is not included in the data.\n"
+"\n"
+" name=content\n"
+" This will make curl URL-encode the content part and pass\n"
+" that on. Note that the name part is expected to be URL-\n"
+" encoded already.\n"
+"\n"
+" @filename\n"
+, stdout);
+ fputs(
+" This will make curl load data from the given file\n"
+" (including any newlines), URL-encode that data and pass\n"

+" appended, resulting in name=urlencoded-file-content. Note\n"
+" that the name is expected to be URL-encoded already.\n"
+"\n"
+" --digest\n"
+" (HTTP) Enables HTTP Digest authentication. This is a authentica-\n"
+" tion that prevents the password from being sent over the wire in\n"
+" clear text. Use this in combination with the normal -u/--user\n"
+" option to set user name and password. See also --ntlm, --negoti-\n"

+" If this option is used several times, the following occurrences\n"
+" make no difference.\n"
+"\n"
+" --disable-eprt\n"
+" (FTP) Tell curl to disable the use of the EPRT and LPRT commands\n"
+" when doing active FTP transfers. Curl will normally always first\n"
+" attempt to use EPRT, then LPRT before using PORT, but with this\n"
+, stdout);
+ fputs(
+" option, it will use PORT right away. EPRT and LPRT are exten-\n"
+" sions to the original FTP protocol, and may not work on all\n"
+" servers, but they enable more functionality in a better way than\n"
+" the traditional PORT command.\n"
+"\n"
+" Since curl 7.19.0, --eprt can be used to explicitly enable EPRT\n"
+" again and --no-eprt is an alias for --disable-eprt.\n"
+"\n"
+, stdout);

+" How to post a form with curl, lesson #1:\n"
+"\n"
+" Dig out all the <input> tags in the form that you want to fill in. (There's\n"

+" be properly URL encoded. That means you replace space with + and that you\n"
+" write weird letters with %XX where XX is the hexadecimal representation of\n"
+" the letter's ASCII code.\n"
+"\n"
+" Example:\n"
+"\n"
+" (page located at http://www.formpost.com/getthis/\n"
+"\n"
+, stdout);
+ fputs(
+" <form action=\"post.cgi\" method=\"post\">\n"

+" <input name=ding value=\"submit\">\n"
+" </form>\n"
+"\n"
+" We want to enter user 'foobar' with password '12345'.\n"
+"\n"
+" To post to this, you enter a curl command line like:\n"
+"\n"
+" curl -d \"user=foobar&pass=12345&id=blablabla&ding=submit\" (continues)\n"
+" http://www.formpost.com/getthis/post.cgi\n"
+"\n"
+"\n"
+, stdout);
+ fputs(
+" While -d uses the application/x-www-form-urlencoded mime-type, generally\n"
+" understood by CGI's and similar, curl also supports the more capable\n"
+" multipart/form-data type. This latter type supports things like file upload.\n"
+"\n"
+" -F accepts parameters like -F \"name=contents\". If you want the contents to\n"
+" be read from a file, use <@filename> as contents. When specifying a file,\n"
+" you can also specify the file content type by appending ';type=<mime type>'\n"
+, stdout);
+ fputs(
+" to the file name. You can also post the contents of several files in one\n"
+" field. For example, the field name 'coolfiles' is used to send three files,\n"
+" with different content types using the following syntax:\n"
+"\n"
+" curl -F \"coolfiles=@fil1.gif;type=image/gif,fil2.txt,fil3.html\" \\\n"
+" http://www.post.com/postit.cgi\n"
+"\n"
+" If the content-type is not specified, curl will try to guess from the file\n"
+" extension (it only knows a few), or use the previously specified type (from\n"
+, stdout);
+ fputs(
+" an earlier file if several files are specified in a list) or else it will\n"
+" using the default type 'text/plain'.\n"
+"\n"
+" Emulate a fill-in form with -F. Let's say you fill in three fields in a\n"
+" form. One field is a file name which to post, one field is your name and one\n"
+" field is a file description. We want to post the file we have written named\n"
+" \"cooltext.txt\". To let curl do the posting of this data instead of your\n"
+" favourite browser, you have to read the HTML source of the form page and\n"
+, stdout);
+ fputs(
+" find the names of the input fields. In our example, the input field names\n"
+" are 'file', 'yourname' and 'filedescription'.\n"
+"\n"
+" curl -F \"file=@cooltext.txt\" -F \"yourname=Daniel\" \\\n"
+" -F \"filedescription=Cool text file with cool text inside\" \\\n"
+" http://www.post.com/postit.cgi\n"
+"\n"
+" To send two files in one post you can do it in two ways:\n"
+"\n"
+" 1. Send multiple files in a single \"field\" with a single field name:\n"
+"\n"
+" curl -F \"pictures=@dog.gif,cat.gif\"\n"
+"\n"
+, stdout);
+ fputs(
+" 2. Send two fields with two field names:\n"
+"\n"
+" curl -F \"docpicture=@dog.gif\" -F \"catpicture=@cat.gif\"\n"
+"\n"
+" To send a field value literally without interpreting a leading '@'\n"
+" or '<', or an embedded ';type=', use --form-string instead of\n"
+" -F. This is recommended when the value is obtained from a user or\n"
+" some other unpredictable source. Under these circumstances, using\n"
+" -F instead of --form-string would allow a user to trick curl into\n"
+" uploading a file.\n"

+" cookie should expire (\"expire=DATE\"), for what domain to use it\n"
+" (\"domain=NAME\") and if it should be used on secure connections only\n"
+" (\"secure\").\n"
+"\n"
+" If you've received a page from a server that contains a header like:\n"
+" Set-Cookie: sessionid=boo123; path=\"/foo\";\n"
+"\n"
+" it means the server wants that first pair passed on when we get anything in\n"
+" a path beginning with \"/foo\".\n"
+"\n"
+, stdout);
+ fputs(
+" Example, get a page that wants my name passed in a cookie:\n"
+"\n"
+" curl -b \"name=Daniel\" www.sillypage.com\n"

+" sessions. If you get cookies from a server and store them in a file in a\n"
+" manner similar to:\n"
+"\n"
+" curl --dump-header headers www.example.com\n"
+"\n"
+" ... you can then in a second connect to that (or another) site, use the\n"
+" cookies from the 'headers' file like:\n"
+"\n"
+" curl -b headers www.example.com\n"
+"\n"
+, stdout);
+ fputs(
+" While saving headers to a file is a working way to store cookies, it is\n"
+" however error-prone and not the preferred way to do this. Instead, make curl\n"
+" save the incoming cookies using the well-known netscape cookie format like\n"
+" this:\n"
+"\n"
+" curl -c cookies.txt www.example.com\n"
+"\n"
+" Note that by specifying -b you enable the \"cookie awareness\" and with -L\n"
+" you can make curl follow a location: (which often is used in combination\n"

+" with cookies). So that if a site sends cookies and a location, you can\n"
+" use a non-existing file to trigger the cookie awareness like:\n"

+" curl -L -b empty.txt www.example.com\n"
+"\n"

+" without URL by making a config file similar to:\n"
+"\n"
+" # default url to get\n"
+" url = \"http://help.with.curl.com/curlhelp.html\"\n"
+"\n"
+" You can specify another config file to be read by using the -K/--config\n"

+, stdout);
+ fputs(
+" tables etc:\n"
+"\n"
+" echo \"user = user:passwd\" | curl -K - http://that.secret.site.com\n"
+"\n"
+"EXTRA HEADERS\n"
+"\n"
+" When using curl in your own very special programs, you may end up needing\n"
+" to pass on your own custom headers when getting a web page. You can do\n"
+" this by using the -H flag.\n"
+"\n"
+" Example, send the header \"X-you-and-me: yes\" to the server when getting a\n"
+" page:\n"
+"\n"
+" curl -H \"X-you-and-me: yes\" www.love.com\n"
+"\n"
+" This can also be useful in case you want curl to send a different text in a\n"
+, stdout);
+ fputs(
+" header than it normally does. The -H header you specify then replaces the\n"
+" header curl would normally send. If you replace an internal header with an\n"
+" empty one, you prevent that header from being sent. To prevent the Host:\n"
+" header from being used:\n"
+"\n"
+" curl -H \"Host:\" www.server.com\n"
+"\n"
+"FTP and PATH NAMES\n"
+"\n"
+" Do note that when getting files with the ftp:// URL, the given path is\n"
+" relative the directory you enter. To get the file 'README' from your home\n"
+" directory at your ftp site, do:\n"
+"\n"
+, stdout);
+ fputs(
+" curl ftp://user:passwd@my.site.com/README\n"
+"\n"
+" But if you want the README file from the root directory of that very same\n"
+" site, you need to specify the absolute file name:\n"
+"\n"
+" curl ftp://user:passwd@my.site.com//README\n"
+"\n"
+" (I.e with an extra slash in front of the file name.)\n"
+"\n"
+"SFTP and SCP and PATH NAMES\n"
+"\n"
+" With sftp: and scp: URLs, the path name given is the absolute name on the\n"
+" server. To access a file relative to the remote user's home directory,\n"
+, stdout);
+ fputs(
+" prefix the file with /~/ , such as:\n"
+"\n"
+" curl -u $USER sftp://home.example.com/~/.bashrc\n"
+"\n"
+"FTP and firewalls\n"
+"\n"
+" The FTP protocol requires one of the involved parties to open a second\n"
+" connection as soon as data is about to get transfered. There are two ways to\n"
+" do this.\n"
+"\n"
+" The default way for curl is to issue the PASV command which causes the\n"
+" server to open another port and await another connection performed by the\n"
+, stdout);
+ fputs(
+" client. This is good if the client is behind a firewall that don't allow\n"
+" incoming connections.\n"
+"\n"
+" curl ftp.download.com\n"
+"\n"
+" If the server for example, is behind a firewall that don't allow connections\n"
+" on other ports than 21 (or if it just doesn't support the PASV command), the\n"
+" other way to do it is to use the PORT command and instruct the server to\n"
+" connect to the client on the given (as parameters to the PORT command) IP\n"
+" number and port.\n"
+"\n"
+, stdout);
+ fputs(
+" The -P flag to curl supports a few different options. Your machine may have\n"
+" several IP-addresses and/or network interfaces and curl allows you to select\n"
+" which of them to use. Default address can also be used:\n"
+"\n"
+" curl -P - ftp.download.com\n"
+"\n"
+" Download with PORT but use the IP address of our 'le0' interface (this does\n"
+" not work on windows):\n"
+"\n"
+" curl -P le0 ftp.download.com\n"
+"\n"
+" Download with PORT but use 192.168.0.10 as our IP address to use:\n"
+"\n"
+, stdout);
+ fputs(
+" curl -P 192.168.0.10 ftp.download.com\n"
+"\n"
+"NETWORK INTERFACE\n"
+"\n"
+" Get a web page from a server using a specified port for the interface:\n"
+"\n"
+" curl --interface eth0:1 http://www.netscape.com/\n"
+"\n"
+" or\n"
+"\n"
+" curl --interface 192.168.1.10 http://www.netscape.com/\n"
+"\n"
+"HTTPS\n"
+"\n"
+" Secure HTTP requires SSL libraries to be installed and used when curl is\n"
+" built. If that is done, curl is capable of retrieving and posting documents\n"
+" using the HTTPS protocol.\n"
+"\n"
+" Example:\n"
+"\n"
+, stdout);
+ fputs(
+" curl https://www.secure-site.com\n"
+"\n"
+" Curl is also capable of using your personal certificates to get/post files\n"
+" from sites that require valid certificates. The only drawback is that the\n"
+" certificate needs to be in PEM-format. PEM is a standard and open format to\n"
+" store certificates with, but it is not used by the most commonly used\n"
+" browsers (Netscape and MSIE both use the so called PKCS#12 format). If you\n"
+, stdout);
+ fputs(
+" want curl to use the certificates you use with your (favourite) browser, you\n"
+" may need to download/compile a converter that can convert your browser's\n"
+" formatted certificates to PEM formatted ones. This kind of converter is\n"
+" included in recent versions of OpenSSL, and for older versions Dr Stephen\n"
+" N. Henson has written a patch for SSLeay that adds this functionality. You\n"
+" can get his patch (that requires an SSLeay installation) from his site at:\n"
+" http://www.drh-consultancy.demon.co.uk/\n"
+, stdout);
+ fputs(
+"\n"
+" Example on how to automatically retrieve a document using a certificate with\n"
+" a personal password:\n"
+"\n"
+" curl -E /path/to/cert.pem:password https://secure.site.com/\n"
+"\n"
+" If you neglect to specify the password on the command line, you will be\n"
+" prompted for the correct password before any data can be received.\n"
+"\n"
+" Many older SSL-servers have problems with SSLv3 or TLS, that newer versions\n"
+" of OpenSSL etc is using, therefore it is sometimes useful to specify what\n"
+, stdout);
+ fputs(
+" SSL-version curl should use. Use -3, -2 or -1 to specify that exact SSL\n"
+" version to use (for SSLv3, SSLv2 or TLSv1 respectively):\n"
+"\n"
+" curl -2 https://secure.site.com/\n"
+"\n"
+" Otherwise, curl will first attempt to use v3 and then v2.\n"
+"\n"
+" To use OpenSSL to convert your favourite browser's certificate into a PEM\n"
+" formatted one that curl can use, do something like this (assuming netscape,\n"
+" but IE is likely to work similarly):\n"
+"\n"
+" You start with hitting the 'security' menu button in netscape.\n"
+"\n"
+, stdout);
+ fputs(
+" Select 'certificates->yours' and then pick a certificate in the list\n"
+"\n"
+" Press the 'export' button\n"
+"\n"
+" enter your PIN code for the certs\n"
+"\n"
+" select a proper place to save it\n"
+"\n"
+" Run the 'openssl' application to convert the certificate. If you cd to the\n"
+" openssl installation, you can do it like:\n"
+"\n"
+" # ./apps/openssl pkcs12 -in [file you saved] -clcerts -out [PEMfile]\n"
+"\n"
+"\n"
+"RESUMING FILE TRANSFERS\n"
+"\n"
+" To continue a file transfer where it was previously aborted, curl supports\n"
+, stdout);
+ fputs(
+" resume on http(s) downloads as well as ftp uploads and downloads.\n"
+"\n"
+" Continue downloading a document:\n"
+"\n"
+" curl -C - -o file ftp://ftp.server.com/path/file\n"
+"\n"
+" Continue uploading a document(*1):\n"
+"\n"
+" curl -C - -T file ftp://ftp.server.com/path/file\n"
+"\n"
+" Continue downloading a document from a web server(*2):\n"
+"\n"
+" curl -C - -o file http://www.server.com/\n"
+"\n"
+" (*1) = This requires that the ftp server supports the non-standard command\n"
+" SIZE. If it doesn't, curl will say so.\n"
+"\n"
+, stdout);
+ fputs(
+" (*2) = This requires that the web server supports at least HTTP/1.1. If it\n"
+" doesn't, curl will say so.\n"
+"\n"
+"TIME CONDITIONS\n"
+"\n"
+" HTTP allows a client to specify a time condition for the document it\n"
+" requests. It is If-Modified-Since or If-Unmodified-Since. Curl allow you to\n"
+" specify them with the -z/--time-cond flag.\n"
+"\n"
+" For example, you can easily make a download that only gets performed if the\n"
+" remote file is newer than a local copy. It would be made like:\n"
+"\n"
+, stdout);
+ fputs(
+" curl -z local.html http://remote.server.com/remote.html\n"
+"\n"
+" Or you can download a file only if the local file is newer than the remote\n"
+" one. Do this by prepending the date string with a '-', as in:\n"
+"\n"
+" curl -z -local.html http://remote.server.com/remote.html\n"
+"\n"
+" You can specify a \"free text\" date as condition. Tell curl to only download\n"
+" the file if it was updated since January 12, 2012:\n"
+"\n"
+" curl -z \"Jan 12 2012\" http://remote.server.com/remote.html\n"
+"\n"
+, stdout);
+ fputs(
+" Curl will then accept a wide range of date formats. You always make the date\n"
+" check the other way around by prepending it with a dash '-'.\n"
+"\n"
+"DICT\n"
+"\n"
+" For fun try\n"
+"\n"
+" curl dict://dict.org/m:curl\n"
+" curl dict://dict.org/d:heisenbug:jargon\n"
+" curl dict://dict.org/d:daniel:web1913\n"
+"\n"
+" Aliases for 'm' are 'match' and 'find', and aliases for 'd' are 'define'\n"
+" and 'lookup'. For example,\n"
+"\n"
+" curl dict://dict.org/find:curl\n"
+"\n"

+" protocol) are\n"
+"\n"
+" curl dict://dict.org/show:db\n"
+" curl dict://dict.org/show:strat\n"
+"\n"
+" Authentication is still missing (but this is not required by the RFC)\n"
+"\n"
+"LDAP\n"
+"\n"
+" If you have installed the OpenLDAP library, curl can take advantage of it\n"
+" and offer ldap:// support.\n"
+"\n"
+" LDAP is a complex thing and writing an LDAP query is not an easy task. I do\n"
+, stdout);
+ fputs(
+" advice you to dig up the syntax description for that elsewhere. Two places\n"
+" that might suit you are:\n"
+"\n"
+" Netscape's \"Netscape Directory SDK 3.0 for C Programmer's Guide Chapter 10:\n"
+" Working with LDAP URLs\":\n"
+" http://developer.netscape.com/docs/manuals/dirsdk/csdk30/url.htm\n"
+"\n"
+" RFC 2255, \"The LDAP URL Format\" http://curl.haxx.se/rfc/rfc2255.txt\n"
+"\n"
+" To show you an example, this is now I can get all people from my local LDAP\n"
+" server that has a certain sub-domain in their email address:\n"
+"\n"
+, stdout);
+ fputs(
+" curl -B \"ldap://ldap.frontec.se/o=frontec??sub?mail=*sth.frontec.se\"\n"
+"\n"
+" If I want the same info in HTML format, I can get it by not using the -B\n"
+" (enforce ASCII) flag.\n"
+"\n"
+"ENVIRONMENT VARIABLES\n"
+"\n"
+" Curl reads and understands the following environment variables:\n"
+"\n"
+" http_proxy, HTTPS_PROXY, FTP_PROXY\n"
+"\n"
+" They should be set for protocol-specific proxies. General proxy should be\n"
+" set with\n"
+"\n"
+" ALL_PROXY\n"
+"\n"
+" A comma-separated list of host names that shouldn't go through any proxy is\n"
+, stdout);
+ fputs(
+" set in (only an asterisk, '*' matches all hosts)\n"
+"\n"
+" NO_PROXY\n"

+" If the host name matches one of these strings, or the host is within the\n"
+" domain of one of these strings, transactions with that node will not be\n"
+" proxied.\n"
+"\n"
+"\n"
+" The usage of the -x/--proxy flag overrides the environment variables.\n"
+"\n"
+"NETRC\n"
+"\n"
+" Unix introduced the .netrc concept a long time ago. It is a way for a user\n"
+" to specify name and password for commonly visited ftp sites in a file so\n"
+, stdout);
+ fputs(
+" that you don't have to type them in each time you visit those sites. You\n"
+" realize this is a big security risk if someone else gets hold of your\n"
+" passwords, so therefore most unix programs won't read this file unless it is\n"
+" only readable by yourself (curl doesn't care though).\n"
+"\n"
+" Curl supports .netrc files if told so (using the -n/--netrc and\n"
+" --netrc-optional options). This is not restricted to only ftp,\n"
+" but curl can use it for all protocols where authentication is used.\n"
+"\n"
+, stdout);
+ fputs(
+" A very simple .netrc file could look something like:\n"
+"\n"
+" machine curl.haxx.se login iamdaniel password mysecret\n"
+"\n"
+"CUSTOM OUTPUT\n"
+"\n"
+" To better allow script programmers to get to know about the progress of\n"
+" curl, the -w/--write-out option was introduced. Using this, you can specify\n"
+" what information from the previous transfer you want to extract.\n"
+"\n"
+" To display the amount of bytes downloaded together with some text and an\n"
+" ending newline:\n"
+"\n"
+, stdout);
+ fputs(
+" curl -w 'We downloaded %{size_download} bytes\\n' www.download.com\n"
+"\n"
+"KERBEROS FTP TRANSFER\n"
+"\n"
+" Curl supports kerberos4 and kerberos5/GSSAPI for FTP transfers. You need\n"
+" the kerberos package installed and used at curl build time for it to be\n"
+" used.\n"
+"\n"
+" First, get the krb-ticket the normal way, like with the kinit/kauth tool.\n"
+" Then use curl in way similar to:\n"
+"\n"
+" curl --krb private ftp://krb4site.com -u username:fakepwd\n"
+"\n"
+, stdout);
+ fputs(
+" There's no use for a password on the -u switch, but a blank one will make\n"
+" curl ask for one and you already entered the real password to kinit/kauth.\n"
+"\n"
+"TELNET\n"
+"\n"
+" The curl telnet support is basic and very easy to use. Curl passes all data\n"
+" passed to it on stdin to the remote server. Connect to a remote telnet\n"
+" server using a command line similar to:\n"
+"\n"
+" curl telnet://remote.server.com\n"
+"\n"
+" And enter the data to pass to the server on stdin. The result will be sent\n"
+, stdout);
+ fputs(
+" to stdout or to the file you specify with -o.\n"
+"\n"
+" You might want the -N/--no-buffer option to switch off the buffered output\n"
+" for slow connections or similar.\n"
+"\n"
+" Pass options to the telnet protocol negotiation, by using the -t option. To\n"
+" tell the server we use a vt100 terminal, try something like:\n"
+"\n"
+" curl -tTTYPE=vt100 telnet://remote.server.com\n"
+"\n"
+" Other interesting options for it -t include:\n"
+"\n"
+" - XDISPLOC=<X display> Sets the X display location.\n"
+"\n"
+, stdout);
+ fputs(
+" - NEW_ENV=<var,val> Sets an environment variable.\n"
+"\n"
+" NOTE: the telnet protocol does not specify any way to login with a specified\n"
+" user and password so curl can't do that automatically. To do that, you need\n"
+" to track when the login prompt is received and send the username and\n"
+" password accordingly.\n"
+"\n"
+"PERSISTENT CONNECTIONS\n"
+"\n"
+" Specifying multiple files on a single command line will make curl transfer\n"
+" all of them, one after the other in the specified order.\n"
+"\n"
+, stdout);
+ fputs(
+" libcurl will attempt to use persistent connections for the transfers so that\n"
+" the second transfer to the same host can use the same connection that was\n"
+" already initiated and was left open in the previous transfer. This greatly\n"
+" decreases connection time for all but the first transfer and it makes a far\n"
+" better use of the network.\n"
+"\n"
+" Note that curl cannot use persistent connections for transfers that are used\n"
+" in subsequence curl invokes. Try to stuff as many URLs as possible on the\n"
+, stdout);
+ fputs(
+" same command line if they are using the same host, as that'll make the\n"
+" transfers faster. If you use a http proxy for file transfers, practically\n"
+" all transfers will be persistent.\n"
+"\n"
+"MULTIPLE TRANSFERS WITH A SINGLE COMMAND LINE\n"
+"\n"
+" As is mentioned above, you can download multiple files with one command line\n"
+" by simply adding more URLs. If you want those to get saved to a local file\n"
+" instead of just printed to stdout, you need to add one save option for each\n"
+, stdout);
+ fputs(
+" URL you specify. Note that this also goes for the -O option (but not\n"
+" --remote-name-all).\n"
+"\n"
+" For example: get two files and use -O for the first and a custom file\n"
+" name for the second:\n"
+"\n"
+" curl -O http://url.com/file.txt ftp://ftp.com/moo.exe -o moo.jpg\n"
+"\n"
+" You can also upload multiple files in a similar fashion:\n"
+"\n"
+" curl -T local1 ftp://ftp.com/moo.exe -T local2 ftp://ftp.com/moo2.txt\n"
+"\n"
+"IPv6\n"
+"\n"
+" curl will connect to a server with IPv6 when a host lookup returns an IPv6\n"
+, stdout);
+ fputs(
+" address and fall back to IPv4 if the connection fails. The --ipv4 and --ipv6\n"
+" options can specify which address to use when both are available. IPv6\n"
+" addresses can also be specified directly in URLs using the syntax:\n"
+"\n"
+" http://[2001:1890:1112:1::20]/overview.html\n"
+"\n"
+" When this style is used, the -g option must be given to stop curl from\n"
+" interpreting the square brackets as special globbing characters. Link local\n"
+, stdout);
+ fputs(
+" and site local addresses including a scope identifier, such as fe80::1234%1,\n"
+" may also be used, but the scope portion must be numeric and the percent\n"
+" character must be URL escaped. The previous example in an SFTP URL might\n"
+" look like:\n"
+"\n"
+" sftp://[fe80::1234%251]/\n"
+"\n"
+" IPv6 addresses provided other than in URLs (e.g. to the --proxy, --interface\n"
+" or --ftp-port options) should not be URL encoded.\n"
