NAME
       CURLINFO_EFFECTIVE_URL - get the last used URL

SYNOPSIS
       #include <curl/curl.h>

       CURLcode  curl_easy_getinfo(CURL  *handle, CURLINFO_EFFECTIVE_URL, char
       **urlp);

DESCRIPTION
       Pass in a pointer to a char pointer and get  the  last  used  effective
       URL.

       In  cases  when  you've  asked libcurl to follow redirects, it may very
       well not be the same value you set with CURLOPT_URL(3).

       The urlp pointer will be NULL or pointing to private  memory  you  MUST
       NOT free - it gets freed when you call curl_easy_cleanup(3) on the cor-
       responding CURL handle.
