Re: [squid-users] Blocking proxy bypass

Use iptables to forward any port 80 requests to your squid.
Read up on transparent caching. (Accelaration)
In the documentation from visolve.com there are many examples
on it. You should look on the website aswell. http://www.squid-cache.org
Redirecting will make sure that _NO_ port 80 traffic can get past your
cache.
