NAMECURLOPT_HEADEROPT - send HTTP headers to both proxy and host or separately SYNOPSIS#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HEADEROPT, long bitmask); DESCRIPTIONPass 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) are used in requests both to servers and proxies. With this option enabled, CURLOPT_PROXYHEADER(3) does 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 sends both server headers and proxy headers. When doing CONNECT, libcurl sends CURLOPT_PROXYHEADER(3) headers only to the proxy and then CURLOPT_HTTPHEADER(3) headers only to the server. DEFAULTCURLHEADER_SEPARATE (changed in 7.42.1, used CURLHEADER_UNIFIED before then) PROTOCOLSThis functionality affects http only EXAMPLEint main(void) { AVAILABILITYAdded in curl 7.37.0 RETURN VALUEcurl_easy_setopt(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3). SEE ALSOCURLOPT_HTTPHEADER(3), CURLOPT_PROXYHEADER(3)
