> When creating my own implementation of ActionMapper, I have no way to tell the FilterDispatcher to redirect to a different page. I am creating an alias in effect.
> Here's what is going on:
> 1. I invoke the superclass to match an action mapping. if found, return.
> 2. Match again adding "/index.action" to the servlet path. if found, return.
> 3. Match again adding "index.action" (no slash) to the servlet path. if found, return.
> Aside from the obvious inefficiencies to be resolve, it should be plain what my intent is. I am executing the index action for a directory path, but there's no good way to get #3 to issue a redirect. URIs ending in /foo should become /foo/ in the browser.
> Therefore, I pull a page from the Tapestry book. You can throw a RedirectException with a path and a temporary/permanent flag to set the correct HTTP status.
