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...
