[Zope] Redirect to a specific page

Hi, Is it possible to redirect to a specific page no matter what the user asks for? I mean the browser could request the url http://foo.bar.com/luser and I would redirect it to http://foo.bar.com/template?username=luser The problem is that when I request a URL that doesn't exist it reports a 'Not found' error. -- Konstantinos Margaritis Bullet S.A.
