The script is powered by PHP and MySQL, and uses the following PHP libraries;
You will need all three of those installed and running.
cURL has been proven faster than fsockopen (which is used by phproxy, and something similiar is used for cgiproxy)
You also have the option to specify an adsense and a ypn client id, so that it will rewrite the ads brought to you by the proxy off of other websites.
For example, if Johnny visits www.greycobra.com, their ads would be rewritten with your own, so if Johnny clicks one, that's your click.
The script also features an image cache system, so users can get the best load times out of your script.
