9 Calling this function causes the WebMCP to do a 303 HTTP redirect after the current view or action and all filters have finished execution. If routing mode "redirect" has been chosen, then this function is called automatically after an action and all its filters have finished execution. Calling request.redirect{...} (or request.forward{...}) explicitly inside an action will cause routing information from the browser to be ignored. To preserve GET/POST parameters of an action, use request.forward{...} instead. Currently no redirects to external (absolute) URLs are possible, there will be an implementation in future though.
