.SH NAME
|
||
|
|
CURLOPT_PROXYAUTH \- HTTP proxy authentication methods
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYAUTH, long bitmask);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a long as parameter, which is set to a bitmask, to tell libcurl which
|
||
|
|
HTTP authentication method(s) you want it to use for your proxy
|
||
|
|
authentication. If more than one bit is set, libcurl first queries the site to
|
||
|
|
see what authentication methods it supports and then it picks the best one you
|
||
|
|
allow it to use. For some methods, this induces an extra network round\-trip.
|
||
|
|
Set the actual name and password with the \fICURLOPT_PROXYUSERPWD(3)\fP
|
||
|
|
option.
|
||
|
|
|
||
|
|
The bitmask can be constructed by the bits listed and described in the
|
||
|
|
\fICURLOPT_HTTPAUTH(3)\fP man page.
|
||
|
|
