Re: [twsocket] Writing a transparent HTTP proxy

Re: [twsocket] Writing a transparent HTTP proxy
Hi! Transparent proxy works as mediator, listen all incoming request on port 80 or any predefined ports. Then check if page in cache and if not ask site for page, move it cache and returns to caller. Caller don't know is proxy or not, because it is transparently for him.
