Subject RE: altering the request URI in a filter
Date Tue, 03 Sep 2002 18:21:26 GMT
OK, I'm confused now. Your original question was about how you could alter
the request URI in a filter. Now, however, you seem to be asking about how
you can alter the request URI in a Struts Action class or in your own
version of the Struts RequestProcessor. What are you really trying to do?

If you want to modify what the request object looks like to everyone, using
a filter, my previous answer applies: Write a request wrapper which returns
a different value than the original from methods such as getRequestURI().

If you want to do something inside of Struts, you'll have to make do with
the RequestDispatcher, as someone else suggested.
