RequestDispatcher and stuff

Question

          Hiyas,
          I use a RequestDispatcher to chain up a couple of servlets which then
          forward off to a jsp page.
          I've also mapped the first servlet to "/index.html".
          Now, when the request "index.html" I go through the servlet chain and
          end up at my target jsp, but my url doesn't change. It still points to
          "/index.html". I want this to change.
          Is there some way I can do this? I want to force this to happen..

Yo man :-),
          the only way to change the url is to send a redirect to the browser. How
          should the browser know of your dispatches otherwise? Why do you want to
          change the url? Usually the last point of your chain won't be able to
          deliver the same results if you directly point to that URL.
          Consider e.g.:
          Controllerservlet (mapped to index.html, reads URL parameters e.g
          |
          |
          Dispatch 1 (does some stuff, e.g. calculations etc.)
          |
          |
          Dispatch 2 (produces what is finally sent to the browser)
          If you'd change the URL to Dispatch 2 a refresh would not again run the
          whole chain of dispatches, so how would that help??
          Cheerios,
          Daniel
