php question
 

there is a page site.com/redirect.php?id=xxx where xxx is between 1 and 1000
i don't know where redirect.php is redirecting (is not my site)
i'm trying to make a php script to find where site.com/redirect.php?id=xxx is redirecting for each value of xxx

any idee how do i make this?

Try http://web-sniffer.net/

use CURL with CURLOPT_FOLLOWLOCATION option in 0 and look for headers
