Those are some fine points. I presume that in all cases, you have to have your webserver not check for the existence of a file before handing off the request.
I'm curious about the efficiency argument there. I can see your point about the webserver not having to look at calls for a js file or css file or what have you, but the lookup in the url rewriter is usually a pretty straight forward regex with exclusion rules for file extensions (css, js, gif, etc). How much overhead do you think that adds? Versus onmissingtemplate() which will only run when a CF file is requested, but it will have to look for the existence of a file before firing the handler. If you are running through a rewriter, you are probably sending every request to a single file (index.cfm) or perhaps a couple files, so the existence of that file will probably be cached. But if you are throwing a bunch of urls at cf that all look like different file names "/my-article-1.cfm, /my-article-2.cfm, etc) then it will have to look for the existence of every unique url before firing the handler. Have you done any overhead comparison between the two methods?
