Two notes: 1. Be careful when modifying ActionForwards to make sure that you aren't modifying the shared, system-wide instance. That can be a nasty side effect. You can make a copy of the ActionForward object, change it, and return the copy from your Action.execute() method to get around this issue.
2. Servlet Filters and HttpRequestWrappers do provide a means to mess with the request parameters (since you can override getParameter()). However, I doubt that is useful in this context. -Max On Wed, 2005-09-14 at 09:23 -0400, Frank W.
