set and use internal comment variable

Hi! I've a setup where it is possible to deny a request at various places for different reasons. I use sql_log in post-auth to log the replies. It would now be nice to add a comment variable which I fill at the various stations, that can deny a request, so I know why a request was denied. How should I try to solve this? Or is there an even better way without a comment variable to do something like this? Thx for your help. Mit freundlichen Grüßen Robert Penz ---------------------------------------------------- Dipl.
