Subject: redirecting old context uris when moving context
Hi
I was formerly hosting a web application at
http://somehost/somecontext
which I am now hosting at
http://somehost
so that the context is now ROOT, instead of somecontext.
Is there a way of mapping / redirecting 'old' URI from somecontext to the
ROOT, so that
http://somehost/somecontext/someuri
becomes
http://somehost/someuri
This would be advantageous to me because bookmarked / search-engine
listings for /someuri are now giving a 404, which I'd prefer to be a
redirect. There is also the matter of links on other websites.
I was looking through my code and I've never had to do it... but I'm
thinking it must be a common thing.
As one person said redirecting in the Apache front end is an option, but I'm
wondering if its not possible to do it at TC level..
I would try this....
Make a servlet in the old Webapp One (somecontext)....
Map all the requests to it....
In doGet...
protected void doGet(HttpServletRequest req, HttpServletResponse res)
try this....
ServletContext appTwoCtx=this.getServletContext().getContext("/ROOT");
RequestDispatcher dispatcherTwo =
appTwoCtx.getRequestDispatcher(req.getContextPath()); //Will have to remove
the CONTEXT... I think
dispatcher .forward(req, res);
Cant see why that shouldnt work.... ie all requests coming into the old app
are just sent to root...
Maybe for top pages its ok.... because I dont thhink sessions would tranfer
well like this...
Dispatch has the advantage of being direct... ie it goes directly to the
other webapp..
If this doesnt work.... then at worst you will replace the dispatch with
response.sendRedirect(urlLocation); //after modifying the URL
and all that means it that it will round trip through the browser...
Maybe?
Let us know if the dipatch worked across webapps.... good luck...
Thanks in advance
Dan Garland
