snarasingh:In my case both the clients will use even the same virtual directory.
Leo Tang - MSFT:you can isolate the client2 by using the "cs-uri-stem" filed. The "cs-uri-stem" begins with "/client’s name".
Because they are using the same virtual directory, this will not work.
snarasingh:I'm trying hard how to seperate out the log for each client...
You have quite a problem then. The application should have been designed to take usage statistics into account. There doesn't seem to be any way to identify from the IIS log what client content is being served. Does the site use the same domain name for each client?
