PHProxy is a web HTTP (for now; FTP is not supprted yet) 
proxy programmed in PHP designed to bypass firewalls and 
other proxy restrictions through a web interface very similar 
to the popular CGIProxy.

The server that this script runs on simply acts as a medium 
that retrives resources for you. The only IP address shown 
will be the server's IP address. So basically, it is indirect 
browsing. The only catch being that the server has to has access 
to those otherwise inaccessible resources.
