Follow http 3xx redirects
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FOLLOWLOCATION, long enable);
A parameter set to 1 tells the library to follow any Location: header that the server sends as part of a HTTP header in a 3xx response.
This means that libcurl will re-send the same request on the new location and follow new Location: headers all the way until no more such headers are returned. CURLOPT_MAXREDIRS(3) can be used to limit the number of redirects libcurl will follow.
libcurl can limit to what protocols it will automatically follow. The accepted protocols are set with CURLOPT_REDIR_PROTOCOLS(3) and it excludes the FILE protocol by default.
Along with HTTP
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
