.TH CURLOPT_HEADEROPT 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_HEADEROPT \- set how to send HTTP headers
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HEADEROPT, long bitmask);
|
|
.SH DESCRIPTION
|
|
Pass a long that is a bitmask of options of how to deal with headers. The two
|
|
mutually exclusive options are:
|
|
|
|
\fBCURLHEADER_UNIFIED\fP - the headers specified in
|
|
\fICURLOPT_HTTPHEADER(3)\fP will be used in requests both to servers and
|
|
proxies. With this option enabled, \fICURLOPT_PROXYHEADER(3)\fP will not have
|
|
any effect.
|
|
|
|
\fBCURLHEADER_SEPARATE\fP - makes \fICURLOPT_HTTPHEADER(3)\fP headers only get
|
|
sent to a server and not to a proxy. Proxy headers must be set with
|
|
\fICURLOPT_PROXYHEADER(3)\fP 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 \fICURLOPT_PROXYHEADER(3)\fP
|
|
headers only to the proxy and then \fICURLOPT_HTTPHEADER(3)\fP headers only to
|
|
the server.
|
|
.SH DEFAULT
|
|
CURLHEADER_SEPARATE (changed in 7.42.1, used CURLHEADER_UNIFIED before then)
|
|
.SH PROTOCOLS
|
|
HTTP
|

.SH EXAMPLE

|
|
curl_easy_setopt(curl, CURLOPT_PROXY, "http://localhost:8080");
|
|
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, list);
|
|
|
|
/* HTTPS over a proxy makes a separate CONNECT to the proxy, so tell
|
|
libcurl to not send the custom headers to the proxy. Keep them
|
|
separate! */
