From 845522cadb6ac9d357d68bb022a148a8c3be2e6a Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Fri, 16 Dec 2016 16:02:08 +0100 Subject: preproxy: renamed what was added as SOCKS_PROXY CURLOPT_SOCKS_PROXY -> CURLOPT_PRE_PROXY Added the corresponding --preroxy command line option. Sets a SOCKS proxy to connect to _before_ connecting to a HTTP(S) proxy. --- docs/libcurl/opts/CURLOPT_PRE_PROXY.3 | 69 +++++++++++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 docs/libcurl/opts/CURLOPT_PRE_PROXY.3 (limited to 'docs/libcurl/opts/CURLOPT_PRE_PROXY.3') diff --git a/docs/libcurl/opts/CURLOPT_PRE_PROXY.3 b/docs/libcurl/opts/CURLOPT_PRE_PROXY.3 new file mode 100644 index 000000000..035dd3ac6 --- /dev/null +++ b/docs/libcurl/opts/CURLOPT_PRE_PROXY.3 @@ -0,0 +1,69 @@ +.\" ************************************************************************** +.\" * _ _ ____ _ +.\" * Project ___| | | | _ \| | +.\" * / __| | | | |_) | | +.\" * | (__| |_| | _ <| |___ +.\" * \___|\___/|_| \_\_____| +.\" * +.\" * Copyright (C) 1998 - 2016, Daniel Stenberg, , et al. +.\" * +.\" * This software is licensed as described in the file COPYING, which +.\" * you should have received as part of this distribution.

The parameter +should be a char * to a zero terminated string holding the host name or dotted +numerical IP address. A numerical IPv6 address must be written within +[brackets]. + +To specify port number in this string, append :[port] to the end of the host +name. The proxy's port number may optionally be specified with the separate +option \fICURLOPT_PROXYPORT(3)\fP. If not specified, libcurl will default to +using port 1080 for proxies. + +A pre proxy is a SOCKS proxy that curl connects to before it connects to the +HTTP(S) proxy specified in the \fICURLOPT_PROXY\fP option. The pre proxy can +only be a SOCKS proxy. + +The pre proxy string should be prefixed with [scheme]:// to specify which kind +of socks is used. Use socks4://, socks4a://, socks5:// or socks5h:// (the last +one to enable socks5 and asking the proxy to do the resolving, also known as +\fICURLPROXY_SOCKS5_HOSTNAME\fP type) to request the specific SOCKS version to +be used. Otherwise SOCKS4 is used as default. + +Setting the pre proxy string to "" (an empty string) will explicitly disable +the use of a pre proxy. +.SH DEFAULT +Default is NULL, meaning no pre proxy is used. + +When you set a host name to use, do not assume that there's any particular +single port number used widely for proxies. Specify it! +.SH PROTOCOLS +All except file://. Note that some protocols don't do very well over proxy. +.SH EXAMPLE +TODO +.SH AVAILABILITY +Added in 7.52.0 +.SH RETURN VALUE +Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or +CURLE_OUT_OF_MEMORY if there was insufficient heap space. +.SH "SEE ALSO" +.BR CURLOPT_PROXY "(3), " CURLOPT_HTTPPROXYTUNNEL "(3), " + -- cgit v1.2.3
