.TH CURLOPT_AUTOREFERER 3 "17 Jun 2014" libcurl libcurl
.SH NAME
CURLOPT_AUTOREFERER \- automatically update the referer header
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AUTOREFERER, long autorefer);
.fi
.SH DESCRIPTION
Pass a long parameter set to 1 to enable this. When enabled, libcurl will
automatically set the Referer: header field in HTTP requests to the full URL
where it follows a Location: redirect.
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.
.SH DEFAULT
0, disabled

HTTP

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);
}
