This is what I had been reading. So from what it says, they will not be able to open a 2nd browser until the authenticate_ttl is up. That kind of makes things tough, if it is set to so many hours, then they cannot open a 2nd browser up for quite a while once the 1st is closed, but if I set it very low, then they could just be opening browsers up all over the place (which is what I am trying to avoid). It looks like it should clear the cache out out as soon as they log off the browser and reset the ttl. I guess that is more what I am wanting to do. I'll go back through the squid.conf to see if I can find a way to do that. Thanks. Scott
