.TH CURLOPT_PRE_PROXY 3 "16 Nov 2016" "libcurl 7.52.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_PRE_PROXY \- set pre-proxy to use
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PRE_PROXY, char *preproxy);
|
|
.SH DESCRIPTION
|
|
Set the \fIpreproxy\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.
|
|
|
|
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.
