NAME

       CURLOPT_PROXYAUTH - HTTP proxy authentication methods

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYAUTH, long bitmask);

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 will first  query
       the  site  to see what authentication methods it supports and then pick the best one you allow it to use.
       For some methods, this will induce an extra network round-trip. Set the actual name and password with the
       CURLOPT_PROXYUSERPWD(3) option.

       The  bitmask  can  be  constructed  by  or'ing  together  the  bits  fully  listed  and  described in the
       CURLOPT_HTTPAUTH(3) man page.

DEFAULT

       CURLAUTH_BASIC

PROTOCOLS

       HTTP

EXAMPLE

       CURL *curl = curl_easy_init();

         CURLcode ret;
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         /* use this proxy */
         curl_easy_setopt(curl, CURLOPT_PROXY, "http://local.example.com:1080");
         /* allow whatever auth the proxy speaks */
         curl_easy_setopt(curl, CURLOPT_PROXYAUTH, CURLAUTH_ANY);
         /* set the proxy credentials */
         curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD, "james:007");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }
