I am writing an ISAPI filter which provides authentication services. I would like to ensure that any requests I allow through have some additional information logged in the IIS logfile. This will include details on the logged in user to allow later stats generation.
In Apache, I have accomplished this by adding a named "note" the the request, and configuring the log format to include my note in the logfile.
Is there any way I could accomplish the same thing in IIS? I know there is support for writing the cookie value to the logfile, but I'd rather write something more customised.
Cunning ideas welcome...
