Please forgive me if I'm misunderstanding this, but there is still an _internal_ loop with the null request. Consider the two requests '/artichoke/HELLO' and '/artichoke/' - both of which would be loops as far as the browser is concerned. The first results in a redirect to the same address. However, the second results in a hanging request, no response sent to the browser, and a child process which sits in a tight loop consuming CPU until the parent httpd is TERMed. [OK, the rules don't make a great deal of sense on their own, but I actually hit this using similar rules in the midst of a big pile, moving a hierarchy from one location to another and rewriting every file and directory name en route. Don't ask...!] Cheers
