Hi Amy, Let's try to repro it. What is the URL that doesn't work with the Web proxy client configuration and then works with the Firewall client configuration + Web proxy client configuration?

So what's else could it be?

ISA 2004 SP2 only supports GZip encoding. If the server responds with any other form, ISA will drop it. -----Original Message----- From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxx] Sent: Tuesday, February 14, 2006 6:29 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Proxy 502: rejected by the http filter http://www.ISAserver.org Hi Amy, I think it might be a coincidence, unless the firewall client is enabling a Direct Access entry for you.
