Ok, here is the problem, I have an apache web server running on port 80 and a squid proxy running on port 8080. Unfortunately some of the proxy users are behind a firewall that blocks everything but port 80. Is there a way that I can set up the proxy to cache the local web server (running on the same machine) and the rest of the internet on port 80? And, I would like to set it up so that local users do not have to authenticate with the proxy, but everyone else does. Is this possible?
