From 006ff62d8c51f664c167c6337f009f9f65dd8ea7 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Mon, 17 Dec 2018 15:46:56 +0100 Subject: http: added options for allowing HTTP/0.9 responses Added CURLOPT_HTTP09_ALLOWED and --http0.9 for this purpose. For now, both the tool and library allow HTTP/0.9 by default. docs/DEPRECATE.md lays out the plan for when to reverse that default: 6 months after the 7.64.0 release. The options are added already now so that applications/scripts can start using them already now. Fixes #2873 Closes #3383 --- docs/libcurl/opts/CURLOPT_HTTP09_ALLOWED.3 | 58 ++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 docs/libcurl/opts/CURLOPT_HTTP09_ALLOWED.3 (limited to 'docs/libcurl/opts/CURLOPT_HTTP09_ALLOWED.3') diff --git a/docs/libcurl/opts/CURLOPT_HTTP09_ALLOWED.3 b/docs/libcurl/opts/CURLOPT_HTTP09_ALLOWED.3 new file mode 100644 index 000000000..3fa44993a --- /dev/null +++ b/docs/libcurl/opts/CURLOPT_HTTP09_ALLOWED.3 @@ -0,0 +1,58 @@ +.\" ************************************************************************** +.\" * _ _ ____ _ +.\" * Project ___| | | | _ \| | +.\" * / __| | | | |_) | | +.\" * | (__| |_| | _ <| |___ +.\" * \___|\___/|_| \_\_____| +.\" * +.\" * Copyright (C) 1998 - 2018, Daniel Stenberg, , et al. +.\" * +.\" * This software is licensed as described in the file COPYING, which +.\" * you should have received as part of this distribution.
