I offten need such link as db.cgi?db=test&do=search_results&detail=1&ID=239 or longer. I would like to shorten it to: db.cgi?TID=239. It will be more convinent for both user and us.

I know I can use Apache rewrite rule. Or I can modify the DBman. Maybe I can finish it myself. But if an expert such as Alex give a hand. It will be more safe. Because I am not sure whether my modification is safe in mod_perl.
