CURLOPT_AUTOREFERER(3) libcurl CURLOPT_AUTOREFERER(3)
NAME
CURLOPT_AUTOREFERER - automatically update the referer header
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AUTOREFERER, long autorefer);
DESCRIPTION
Pass 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 redi-
rects are done cross-origin or following redirects to insecure proto-
cols. This is considered a minor privacy leak by some.
DEFAULT
0, disabled
PROTOCOLS
HTTP
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
/* follow redirects */
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
/* set Referer: automatically when following redirects */
curl_easy_setopt(curl, CURLOPT_AUTOREFERER, 1L);
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
AVAILABILITY
Along with HTTP
RETURN VALUE
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
