curl the next few years - perhaps

Roadmap of things Daniel Stenberg wants to work on next. It is intended to serve as a guideline for others for information, feedback and possible participation.

HTTP/3

See the QUIC and HTTP/3 wiki page.

ESNI (Encrypted SNI)

See Daniel's post on Support of Encrypted SNI on the mailing list.

HSTS

Complete and merge the existing PR.

Parallel transfers for the curl tool

This will require several new command line options to enable and control.

1. switch to creating a list of all the transfers first before any transfer is done
2. make the transfers using the multi interface
3. optionally fire up more transfers before the previous has completed

Option to refuse HTTPS => HTTP redirects

Possibly as a new bit to CURLOPT_FOLLOWLOCATION ?

Option to let CURLOPT_CUSTOMREQUEST be overridden on redirect

(This is a common problem for people using -X and -L together.)

Possibly as a new bit to CURLOPT_FOLLOWLOCATION ?

Hardcode “localhost”

No need to resolve it. Avoid a risk where this is resolved over the network and actually responds with something else than a local address. Some operating systems already do this. Also: https://tools.ietf.org/html/draft-ietf-dnsop-let-localhost-be-localhost-02

Consider “menu config”-style build feature selection

Allow easier building of custom libcurl versions with only a selected feature where the available features are easily browsable and toggle-able ON/OFF or similar.
