My preferred solution, while not used for this though it could be, is to have Apache use a perl-script as a logging process. In the script I can do any kind of segregation, ignoring, etc. I want to for any entries.

If you really want to look at some moldy code here it is, flog. I don't need a code review though, 'm-k? Just glancing at it makes me cringe. But believe it or not I've been using it continuously since I wrote it oh so long ago. I've been meaning to get around to touching it up a bit, maybe someday...
