intercepting packets for web servers and replying back

hi,

I was wondering how to approach a program which will run on server which is the default gateway and will process all packets that arrive on tcp transport with destination port 80 (which are destined for a webserver somewhere on the internet) and will basically reply back to the client with some html file instead of the original webserver.

any ideas are welcome...

regards.

Sounds like your basic transparent HTTP proxy. Look at squid.
