PC's without proxy setting are routing right through BorderManager
server. I have HTTP (SSL) authentication enabled and Single Signon
enabled. This is allowing students in our disctict to bypass the
upstream content filters. How can I force all PC to go through the
Proxy? We push proxy settings out to the PCs but students have reverted
to using "portable firefox" which does not get our proxy settins and thus
can go anywhere they wish.
