Incidentally, that's how Vignette StoryServer works. You could also do this kind of thing with a transhandler (or mod_rewrite) that checks for the existence of a static file and rewrites the URL if it can't find one. That might be more "correct", but trapping 404 is the best possible performance, since there is no additional code in the response chain if the static file is there. - Perrin
