[Zope] Directory traversal like zope in Apache?

OK, so I'm forced to use Apache when I'd rather use Zope :-) My question is (crossing fingers that someone else has run into this): Does anyone know of a way (other than using pcgi and Zope) to enable Zope-style directory traversals in Apache? This is the one that allows me to put a header_html file at the top level and any references further down the tree will traverse up until it finds a header_html file. I hope I'm not the only person to have needed something like this. I swear I've seen it before, but sadly, Google isn't helping today. -Peter
