| .TH CURLOPT_HTTP09_ALLOWED 3 "August 05, 2019" "libcurl 7.72.0" "curl_easy_setopt options" |
| |
| .SH NAME |
| CURLOPT_HTTP09 \- allow HTTP/0.9 response |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTP09_ALLOWED, long allowed); |
| .SH DESCRIPTION |
| Pass the long argument \fIallowed\fP set to 1L to allow HTTP/0.9 responses. |
| |
| A HTTP/0.9 response is a server response entirely without headers and only a |
| body. You can connect to lots of random TCP services and still get a response |
| that curl might consider to be HTTP/0.9! |
| .SH DEFAULT |
| curl allowed HTTP/0.9 responses by default before 7.66.0 |
| |
| Since 7.66.0, libcurl requires this option set to 1L to allow HTTP/0.9 |
| responses. |
| .SH PROTOCOLS |
| HTTP |
| .SH EXAMPLE |
| .nf |
| CURL *curl = curl_easy_init(); |
| if(curl) { |
| CURLcode ret; |
| curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); |
| curl_easy_setopt(curl, CURLOPT_HTTP09_ALLOWED, 1L); |
| ret = curl_easy_perform(curl); |
| } |
| .fi |
| .SH AVAILABILITY |
| Option added in 7.64.0, present along with HTTP. |
| .SH RETURN VALUE |
| Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not. |
