CURLOPT_PROXYHEADER 3 "May 30, 2017" "libcurl 7.58.0" "curl_easy_setopt options"
NAME
CURLOPT_PROXYHEADER - custom HTTP headers to pass to proxy
SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYHEADER, struct curl_slist *headers);DESCRIPTIONPass a pointer to a linked list of HTTP headers to pass in your HTTP request sent to a proxy. The rules for this list is identical to the CURLOPT_HTTPHEADER(3) option's. The headers set with this option is only ever used in requests sent to a proxy - when there's also a request sent to a host. The first line in a request (containing the method, usually a GET or POST) is NOT a header and cannot be replaced using this option. Only the lines following the request-line are headers. Adding this method line in this list of headers will only cause your request to send an invalid header. Pass a NULL to this to reset back to no custom headers.DEFAULTNULLPROTOCOLSHTTPEXAMPLECURL *curl = curl_easy_init(); struct curl_slist *list; if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); curl_easy_setopt(curl, CURLOPT_PROXY, "http://proxy.example.com:80"); list = curl_slist_append(NULL, "Shoesize: 10"); list = curl_slist_append(list, "Accept:"); curl_easy_setopt(curl, CURLOPT_PROXYHEADER, list); curl_easy_perform(curl); curl_slist_free_all(list); /* free the list again */ }AVAILABILITYAdded in 7.37.0RETURN VALUEReturns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not."SEE ALSO"CURLOPT_HEADEROPT "(3), " CURLOPT_HTTPHEADER "(3), "
