So if I understand correctly, if I unbind the web proxy filter from the
HTTP protocol, the FWC will not use it for connections but the web proxy
clients will unless the direct access rule is invoked?

Hi Ted,
No! Not true. Web proxy clients will always use the Web proxy filter
unless you exclude sites using Direct Access.
That's why you should always configure clients as Web proxy clients and
Firewall clients (server's in general aren't clients, so you don't
install the Firewall client on them).

Hi Tom,
Thanks for the explanation. This is an extremely drastic move (remove
the web proxy filter) from the HTTP protocol! It works but isnt there a
way to exclude it for certain connections or something? this solution
basically lobotomizes ISA and its features....
Thanks
