Act as a firewall and point the browser to your firewall port... all you'll be doing is
1. recieve REQ from client and retransmit to outside world (or deny if URL breaks
rules)
2. recieve from outside world and retransmit to client (or deny if content breaks
rules).
Note that issues with partial page reception make for some ugly censorship...
scenario - You get partway through an html (with a URL that doesn't break the rules)
and have retransmitted to client. Part way through that HTML you locate an offending
word - the client has already recieved the prior part of the page and has begun
downloading images from that page which may themselves contains offending
material. You'd have to retrieve the entire page prior to passing to the client and
this
can slow surfing performance considerably not to mention stretch some timeouts a
little far.

Subject: [DUG-OFFTOPIC]: Intercepting Web Documents..
