Squid Interception Proxying Troubles

[Shawn Badger]

My recommendation would be to set all of the browsers to point to squid
porxy. Then after everyone is pointed to the proxy allow only the proxy
to use port 80 out on the firewall. This will keep the roll out smooth
and then keep anyone with a mis-configured browser from getting out on
the internet.
