The technical reason this happens is that RequestDispatcher.forward() (or
<jsp:forward>) happens only on the server side -- the browser has no clue what
is going on, and only displays the URL it submitted to -- not the URL of the
page you called to create the response.
In various apps I have taken the following approaches to this issue:
* Tell my users "deal with it -- this is a web application, not a
web site, and the URL that you see is totally irrelevant." Of
course, it is incumbent upon the page designer to ensure that
there are always enough navigation controls that the user does
not feel tempted to use the back and forward arrows or bookmarks
within your app.
* Use a framed presentation with only one frame in it -- that way,
the location bar never changes so the user isn't distracted.
* Open your application in a window that does not have a location
bar, so the user isn't distracted.
If you can get away with it, I prefer the first approach :-).
