Probably rather than fsockopen it would be helpful to use the CURL
library to make the connection(s).
You should install the CURL extension to PHP, more information at
http://uk2.php.net/curl and
http://www.zend.com/manual/function.curl-setopt.php (^Find :
CURLOPT_FOLLOWLOCATION)

This page http://curl.haxx.se/mail/curlphp-2002-02/0005.html contains
useful discussion about that. Basically you'll want to set
CURLOPT_FOLLOWLOCATION which will allow CURL to respond to the
redirect header as if it was a browser.

If you're not using CURL then you've got significant extra work to
look at each individual header sent by the redirecting web server to
determine which header is the redirect and which location it's
sending you to (probably using a regex).
