I am trying to browse through a Web Proxy and while my code works very well through some proxies it fails on many others.

One particluar Web Proxy where it fails is: http://www.firewallfilter.com/
Immediately below is the <form> from firewallfilter.com which I am trying to successfully post and below that is the code I am unsuccessfully using.

Any suggestions regarding what I might be doing wrong would be greatly appreciated.

Thank you,
Curt
