NAME

       CURLOPT_PROXYHEADER - set of HTTP headers to pass to proxy

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYHEADER,
                                 struct curl_slist *headers);

DESCRIPTION

       Pass  a  pointer  to  a linked list of HTTP headers to pass in your HTTP request sent to a
       proxy. The rules for this list is identical to the CURLOPT_HTTPHEADER(3) option's.

       The headers set with this option is only ever used in requests sent  to  a  proxy  -  when
       there's also a request sent to a host.

       The first line in a request (containing the method, usually a GET or POST) is NOT a header
       and cannot be replaced using this option. Only the lines following  the  request-line  are
       headers.  Adding  this method line in this list of headers will only cause your request to
       send an invalid header.

       Pass a NULL to this to reset back to no custom headers.

DEFAULT

       NULL

PROTOCOLS

         curl_easy_setopt(curl, CURLOPT_PROXY, "http://proxy.example.com:80");

         list = curl_slist_append(NULL, "Shoesize: 10");
         list = curl_slist_append(list, "Accept:");

         curl_easy_setopt(curl, CURLOPT_PROXYHEADER, list);
