[Zope] Redirects within a Python Script-based Access Rule

How does one write a redirect within a Python Script-based Access Rule? For example, foo.com and foo.net both getting redirected to www.foo.com. Because I already have a virtual hosting environment using an Access Rule and a Virtual Hosting Monster, the easy albeit verbose solution was to create /vhosts/foo_net and /vhosts/foo-www and put a DTML Method "index_html" object: <dtml-call "RESPONSE.redirect('http://www.foo.com')"> in each of those folders and have the Access Rule direct requests to those objects.
