I'm the admin at a private girls school. We have had an issue with instant messaging, so I have been working on blocking it. Before coming here I was given at least a dozen different methods that other schools swear blind work, but none of them seem to do anything. Finally I stumbled across this site, and have been able to configure the HTTP filters to stop the IM plague. But, as soon as the filters were applied, Firefox stopped being able to access the internet. The monitor shows denied against that rule for any FF traffic. So one by one I disabled the new filters, and have been able to narrow it down to the AOL IM filter. The settings for it are
Request Headers User-Agent: Gecko/
For some reason, this is how ISA is seeing FF as well. Has anyone else seen this behaviour or have an laternative. Thankfully, AOL IM doesn't seem to be used here, so I can leave it open for the moment. But I would love to get some feedback on why this is the case.

For students and staff, IE is the default browser. Unfortunately, it is also a gateway to spyware and other problems, even with protection and good intentions. I use FF because it is as stable and vastly more usable than IE as far as I am concerned, but each to their own.
I will look into the headers futher to try and see why there is this odd confusion.

Well, using the Ethereal sniffer has shown that within the header string for FF is Gecko/ It is only a small part of the string, but obviously enough to trip ISA'a http filter. Here's hoping our userbase doesn't realise that AOL is a hole in the wall for the moment.

Gecko is the name of the rendering engine. Try to upgrade to lastest FF first, then...
type in url bar of FF about:config you can here change the user agent string. maybe you will lose your changes after restarting FF and so you have to find for configuration file and write in it. Or just search for one of dozens utility that allows you to manage Firefox
