Hello, I use ISA Server 2004 to publish several web sites from our IntraNet. I collect logging information however the ISA Web Proxy Log has several fields that differ from a Web Server Log (as would be expected). There are also some important fields missing such as the referrer. My question is as follows. Can a filter be created that will create a logfile in the "Standard" W3C Extended Log Format? Has anyone already done this. Thanks Bill
