NAMECURLOPT_AUTOREFERER - automatically update the referer header SYNOPSIS#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AUTOREFERER, long autorefer); DESCRIPTIONPass a long parameter set to 1 to enable this. When enabled, libcurl automatically sets the Referer: header field in HTTP requests to the full URL when it follows a Location: redirect to a new destination. The automatic referer is set to the full previous URL even when redirects are done cross-origin or following redirects to insecure protocols. This is considered a minor privacy leak by some. With CURLINFO_REFERER(3), applications can extract the actually used referer header after the transfer. DEFAULT0, disabled PROTOCOLSThis functionality affects http only EXAMPLEint main(void) { AVAILABILITYAdded in curl 7.1 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).
