This CGI script acts as an HTTP or FTP proxy. Through it, you can retrieve any resource that is accessible from the server it runs on. This is useful when your own access is limited, but you can reach a server that in turn can reach others that you can't. In addition, the user is kept as anonymous as possible from any servers. Common uses include: anonymous proxies similar to The Anonymizer, other personal uses, VPN-like functionality, and others. It's very simple to install, and very configurable.

When an HTML resource is retrieved, it's modified so that all links in it point back through the same proxy, including images, form submissions, and everything else. Once you're using the proxy, you can browse normally and (almost) forget it's there.

Configurable options include text-only support (to save bandwidth), selective cookie and script removal, simple ad filtering, access restriction by server, custom encoding of target URLs and cookies, and more-- there are about 45 options so far. It can run under mod_perl unchanged. It requires Perl 5.004 or later; Perl 5.6.1 or later may be required in future releases.

PHProxy is a Web HTTP proxy programmed in PHP to bypass firewalls and other proxy restrictions through a Web interface very similar to the popular CGIProxy. School/country/company blocked your favorite Website? Look no further!
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 have access to those otherwise inaccessible resources.

After some browsing on the web I came to conclusion CGIProxy offer a lot more than PHPProxy. It works better with javascripts and suppose to be faster so I decide to give it a try.
