CURLOPT_PROXYHEADER(3)     curl_easy_setopt options     CURLOPT_PROXYHEADER(3)

NAME
       CURLOPT_PROXYHEADER - custom 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
