(Added in 7.XXX) +Set the \fIproxy\fP to use for the upcoming request. 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. + +The proxy string may be prefixed with [scheme]:// to specify which kind of +proxy 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. No scheme specified or http://, will be treated as HTTP proxies. + +Without a scheme prefix, \fICURLOPT_PROXYTYPE(3)\fP can be used to specify +which kind of proxy the string identifies. + +When you tell the library to use a HTTP proxy, libcurl will transparently +convert operations to HTTP even if you specify an FTP URL etc. This may have +an impact on what other features of the library you can use, such as +\fICURLOPT_QUOTE(3)\fP and similar FTP specifics that don't work unless you +tunnel through the HTTP proxy. Such tunneling is activated with +\fICURLOPT_HTTPPROXYTUNNEL(3)\fP. + +libcurl respects the environment variables \fBhttp_proxy\fP, \fBftp_proxy\fP, +\fBall_proxy\fP etc, if any of those are set. The \fICURLOPT_PROXY(3)\fP +option does however override any possibly set environment variables. + +Setting the proxy string to "" (an empty string) will explicitly disable the +use of a proxy, even if there is an environment variable set for it. + +A proxy host string can also include protocol scheme (http://) and embedded +user + password. +.SH DEFAULT +Default is NULL, meaning no 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 +Since 7.14.1 the proxy environment variable names can include the protocol +scheme. + +Since 7.21.7 the proxy string supports the socks protocols as "schemes". + +Since 7.50.2, unsupported schemes in proxy strings cause libcurl to return +error. +.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_PROXYPORT "(3), " CURLOPT_HTTPPROXYTUNNEL "(3), " +.BR CURLOPT_PROXYTYPE "(3)" |
