For one client of ours, we blocked all outbound port 80 traffic at the Internet firewall (with some exceptions, as usual!), and then use an "automatic configuration script" that is on the HTTP proxy. When the browser fires up on the end-user PC, it first contacts the proxy server to retrieve the .pac file (auto config script), and based on where it is headed and/or where it came from, it is directed to one of three HTTP proxy servers. Using the auto config script allows us to centrally manage where PC's go for web surfing(via changes to the .pac file). It's the block of direct port 80 access at the Internet firewall that "forces" the PC's to comply with use of the script. I guess they could od manual entry of the proxy settings, but most end users don't quite get how to do that. Additionally, use of active directory group policy "resets" the proxy settings on a regular basis to "force" use the .pac file. Here's a Microsoft Technet article on Automatic Proxy. http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/ierk /Ch21_b.mspx?mfr=true It talks about using Automatic Configuration and Automatic Proxy. We are using the latter only. The proxy you are directed to does not *have* to be a Microsoft proxy. We have some traffic head to a squid proxy on a Solaris machine(long story).
