MessingWithTraversal

When an object is traversed over, this method is called. Key is the object to find, to show normal behaviour, return key. To stop all traversal, return self.

        def __bobo_traverse__(self, REQUEST, key):
                ''' no more traversal '''
                return self

Then inside the __call__ method you can access the REQUEST variable to get the PATH_INFO, or you could do build up a class variable as the __bobo_traverse__ gets called.

        def __call__(self, REQUEST):
                ''' do something '''
                return "%s" % REQUEST{'PATH_INFO'}

The only problem is here that the travesal is actually happening, for each element in the url. It would be nice to simply the traversal at the first chance...

Hmm, perhaps what you want is to hook the publishing traversal instead? See the Interfaces wiki writeup.
