CURLOPT_AUTOREFERER - automatically update the referer header
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AUTOREFERER, long autorefer);
Pass a 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.
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);
}
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
