A "SiteAccess" "AccessRule" can do such things for you.

Look around whether you find some documentation about "AccessRule"s and how to tweak the request object in such a rule.

Thanks Dieter! That indeed did the trick. It took a lot of digging around online (and several times undoing the last edit because it made the folder I was working in uneditable with the management interface) but in the end I was successful. For posterity: A Virtual Host Monster mapping sends any request with the "games" subdomain to a special folder with the following access rule: ##### request = context.REQUEST #determine title (last part of URL) url = request.other['ACTUAL_URL'] if len(url) > 0: if url[-1] == '/': url = url[:-1] splitpath = url.split('/') target = splitpath.pop() #add title as form data to request object request.form['gametitle'] = target #rewrite path - display_game is a Python script in the root of #Zope, so by adding its name to the namestack it will be found. #Not added if I'm editing the script (hack) so I'm not locked out. namestack = request.other['TraversalRequestNameStack'] if namestack[0][:6] != 'ZPytho' and namestack[0][:6] != 'manage': request.other['TraversalRequestNameStack'] = ['display_game'] ##### So far it works well. I can visit games.mydomain.com/Tetris and www.mydomain.com/display_game?gametitle=Tetris interchangably. Aaron
