This might seem rather silly, but I was thinking of opening the log file in sharable read/write mode using a kind of NT service which would start before IIS. That way you could do whatever you want to the file while the NT Service and IIS had it open. But this poses 2 questions 1. Does IIS open the file in lock read/write mode ? If this is the case, then this won't work. 2. What to do when IIS changes log file (at 00:00) ? Well, you could make the NT service create a file just before 00:00 so that IIS would use it also. I'm writing this now, but haven't tested it yet, so probably it wont work. Just my 2 something!
