NAME¶
CURLOPT_HEADEROPT - set how to send HTTP headers
SYNOPSIS¶
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HEADEROPT, long bitmask);
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
CURLOPT_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 headers.
When doing CONNECT, libcurl will send
CURLOPT_PROXYHEADER(3) headers
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)
