Does anyone know if artio can be used to represent .asp based url's (for php / joomla pages) to retain prior pagerank? 301 redirects is the alternative, but if artio could achieve this, it might be a nice way to do it. I'm imagining some apache handler trickery might be needed to?

Am I flogging a dead horse - and would be better to just 301 all the old url's? thoughts all?
