CURLOPT_HEADEROPT(3)       curl_easy_setopt options       CURLOPT_HEADEROPT(3)

NAME
       CURLOPT_HEADEROPT - set how to send HTTP headers

SYNOPSIS
       #include <curl/curl.h>

       CURLcode  curl_easy_setopt(CURL  *handle,  CURLOPT_HEADEROPT, long bit-
       mask);

DESCRIPTION
       Pass a long that is a bitmask of options of how to deal  with  headers.
       The two mutually exclusive options are:

       CURLHEADER_UNIFIED  -  the  headers  specified in CURLOPT_HTTPHEADER(3)
       will be used in requests both to servers and proxies. With this  option
       enabled, CURLOPT_PROXYHEADER(3) will not have any effect.

       CURLHEADER_SEPARATE - makes CURLOPT_HTTPHEADER(3) headers only get sent
       to a server and not to a proxy. Proxy headers must  be  set  with  CUR-
       LOPT_PROXYHEADER(3)  to get used. Note that if a non-CONNECT request is
       sent to a proxy, libcurl will send both server headers and proxy  head-
       ers. When doing CONNECT, libcurl will send CURLOPT_PROXYHEADER(3) head-
       ers only to the proxy and then CURLOPT_HTTPHEADER(3)  headers  only  to
       the server.

DEFAULT
       CURLHEADER_SEPARATE  (changed in 7.42.1, ased CURLHEADER_UNIFIED before
       then)
