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 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
       CURLOPT_PROXYUSERPWD(3) option.

       The bitmask can be constructed by the bits listed and described in the CURLOPT_HTTPAUTH(3) man page.

DEFAULT

       CURLAUTH_BASIC

EXAMPLE

           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);
         }
       }
