Subject Re: Need to modify the URL path of the forward dynamically
Date Mon, 09 Feb 2004 09:23:46 GMT
Andrew's procedure is what my team has done on one project, too. Originally,
we tried getting the ActionForward and changing it directly, but it turns
out that is a shared instance and changing the original was messing up other
requests. After we discovered this problem, we switched to Andrew's scheme
of creating a new ActionForward to return from the Action.

I posted a message today with a note about dynamically adding a query string
to an ActionForward in the "URL does not change even after changing action"
thread. This thread has the details about how to do that.

I am interested to hear from other folks if they have a novel way to do this
(i.e. add a query string to an ActionForward). Anybody got a better way?
