[some links]

I *did* read the links you provided before posting ... they didn't quite 
answer my problem.

Yes, and if you read just a bit above that sentence you will see:

"If, between the % and the variable, you put one or more HTTP status codes, 
the variable will only be logged in the event that the request returns one 
of those status codes."

So this only works for status codes ... what about if I only want to log 
requests between 1am and 3am and only those that returned more than 10k?

Furthermore I think your suggestion will not work anyway. If the status code 
is NOT 404 an empty line will be written to the log file. So I'll end up 
with a log file full of empty lines (non 404 return codes) and some lines 
with information (404 errors). (I'm not 100% sure of this but I think I 
tried it before and that is what happened).

Thanks offering some help though!
