CURLOPT_HEADEROPT(3) curl_easy_setopt options CURLOPT_HEADEROPT(3) NAME CURLOPT_HEADEROPT - send HTTP headers to both proxy and host or sepa- rately 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 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, used CURLHEADER_UNIFIED before then) PROTOCOLS HTTP EXAMPLE CURL *curl = curl_easy_init(); if(curl) { CURLcode ret; struct curl_slist *list; list = curl_slist_append(NULL, "Shoesize: 10"); list = curl_slist_append(list, "Accept:"); curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); 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! */ curl_easy_setopt(curl, CURLOPT_HEADEROPT, CURLHEADER_SEPARATE); ret = curl_easy_perform(curl); curl_slist_free_all(list); curl_easy_cleanup(curl); } AVAILABILITY Added in 7.37.0 RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
