Tells curl to use HTTP version 3 directly to the host and port number used in
the URL. A normal HTTP/3 transaction will be done to a host and then get
redirected via Alt-Svc, but this option allows a user to circumvent that when
you know that the target speaks HTTP/3 on the given host and port.

This option will make curl fail if a QUIC connection cannot be established, it
cannot fall back to a lower HTTP version on its own.
copyright: update all copyright lines and remove year ranges - they are mostly pointless in all major jurisdictions - many big corporations and projects already don't use them - saves us from pointless churn - git keeps history for us - the year range is kept in COPYING checksrc is updated to allow non-year using copyright statements Closes #10205 2023-01-02 20:51:48 +08:00			`c: Copyright (C) Daniel Stenberg, <daniel@haxx.se>, et al.`
docs/cmdline-opts: add copyright and license identifier to each file gen.pl now insists on C: and SPDX-License-Identifier: fields to be present in all files. Closes #9002 2022-06-14 06:12:03 +08:00			`SPDX-License-Identifier: curl`
CURLOPT_HTTP_VERSION: seting this to 3 forces HTTP/3 use directly Even though it cannot fall-back to a lower HTTP version automatically. The safer way to upgrade remains via CURLOPT_ALTSVC. CURLOPT_H3 no longer has any bits that do anything and might be removed before we remove the experimental label. Updated the curl tool accordingly to use "--http3". Closes #4197 2019-08-07 20:17:48 +08:00			`Long: http3`
HTTP3: initial (experimental) support USe configure --with-ngtcp2 or --with-quiche Using either option will enable a HTTP3 build. Co-authored-by: Alessandro Ghedini <alessandro@ghedini.me> Closes #3500 2019-07-22 05:48:58 +08:00			`Tags: Versions`

docs: add categories to all cmdline opts Adapted gen.pl with 'listcats' This commit is a part of "--help me if you can" Closes #5680 2020-07-13 20:15:04 +08:00			`Category: http`
curl.1: provide examples for each option The file format for each option now features a "Example:" header that can provide one or more examples that get rendered appropriately in the output. All options MUST have at least one example or gen.pl complains at build-time. This fix also does a few other minor format and consistency cleanups. Closes #7654 2021-08-31 22:37:14 +08:00			`Example: --http3 $URL`
cmdline/docs: add a required 'multi' keyword for each option The keyword specifies how option works when specified multiple times: - single: the last provided value replaces the earlier ones - append: it supports being provided multiple times - boolean: on/off values - mutex: flag-like option that disable anoter flag The 'gen.pl' script then outputs the proper and unified language for each option's multi-use behavior in the generated man page. The multi: header is requires in each .d file and will cause build error if missing or set to an unknown value. Closes #9759 2022-10-18 16:39:43 +08:00			`Multi: mutex`
