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);
       }
