offline web page browsing

I have several clients and one server in my netwo开发者_如何学Gork. i'd like clients have no direct access to internet. i want that clients send his url request to server via a port ( for example 6098 port or any), then server send those url data (such as html text image etc) to client in response .

do you have any idea or solution for this case? can i develop client side program as web-application ? (using javascript,php) what should i do in server side programm? must i develop a server program? how? is there any kind of this server now developed?

excuse me for my bad english.

Do not develop. Pick a proxy server solution off the self.

Faster, safer, and most probably much more efficient, as the creator surely put a lot of time and people to make the proxy work as smooth, as fast, as secure and as reliably as possible.

You're looking for something called a "web proxy server". There is a list of them in wikipedia:
