I have a client with ISA 2000 server, when the client access the internet through the ISA 2000 firewall (cache mode or integrated mode) the following are added to the header: HTTP_VIA1.0 FIREWALL_SERVER The client doesn't want this information being presented to the website being visited. I am certain that ISA can strip this information from outgoing requests, but cannot seem to find it at the moment. Any help is welcome. This is related to the following: When viewing the page WWW.CENTRAAL.NL the name of the firewall server is shown instead of the site name. It would appear that this is related to the header information listed above.
