[Zope] redirection of whole sub-trees

Is it possible to make this product redirect whole sub-trees? I'm migrating a Zop1 site using cgi under IIS to Zope2 using ZServer. I want to redirect all the "/cgi-bin/zope.exe/(.*)" queries to "/\1" using the grouping syntax. since I'm not using apache I can't use mod_rewrite so this is the only option I can think of at the moment and I can't upgrade until I have the redirection in place. I can do the substitution no prob by changing after line 95 like so for k in self.Mappings.keys(): m = re.match(k, Name) if m: Name = re.sub(k, self.Mappings[k], Name) But "Name" is not the remainder of the url :(
