Tom, As long as the HTTP Security Filter runs first, and XCompress for IIS second there shouldn't be an issue. In other words, the issues you are taking about are when the web server does the compression. Just a note here that between the ISA server and the web server (OWA Server) the communication is NOT compressed. It is just the communication between the client and the ISA server. -Wayne -----Original Message----- From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxx] Sent: Friday, July 09, 2004 4:07 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: XCompress for ISA -- Compression Filter http://www.ISAserver.org Hi Wayne, Does this solve the OWA publishing issue with ISA 2004 and FBA? That is to say, can we enable compression on the published OWA site and still use the ISA FBA feature? What is the effect on exposing the communications to the HTTP Security filter when the data is compressed? From my understanding, compressing the data making it inaccessible to the security filters.
