23 .TH CURLOPT_HEADEROPT 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
25 CURLOPT_HEADEROPT \- set how to send HTTP headers
27 #include <curl/curl.h>
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HEADEROPT, long bitmask);
31 Pass a long that is a bitmask of options of how to deal with headers. The two
32 mutually exclusive options are:
34 \fBCURLHEADER_UNIFIED\fP - the headers specified in
35 \fICURLOPT_HTTPHEADER(3)\fP will be used in requests both to servers and
36 proxies. With this option enabled, \fICURLOPT_PROXYHEADER(3)\fP will not have
39 \fBCURLHEADER_SEPARATE\fP - makes \fICURLOPT_HTTPHEADER(3)\fP headers only get
40 sent to a server and not to a proxy. Proxy headers must be set with
41 \fICURLOPT_PROXYHEADER(3)\fP to get used. Note that if a non-CONNECT request
42 is sent to a proxy, libcurl will send both server headers and proxy
43 headers. When doing CONNECT, libcurl will send \fICURLOPT_PROXYHEADER(3)\fP
44 headers only to the proxy and then \fICURLOPT_HTTPHEADER(3)\fP headers only to
47 CURLHEADER_SEPARATE (changed in 7.42.1, ased CURLHEADER_UNIFIED before then)
55 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
