What is a proxy script?
With the installation of this proxy script in your server, you allow your customers to retrieve any internet resource through it. This is useful when your customer's own access is limited, they can reach your server that in turn can reach others that they 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.
