I handled this situation by creating a special exception, PageHaltException, that I
throw after a sendRedirect() or a forward(). My top-level servlet service method
catches this exception and ignores it (I've taken a page from Craig M's book, and
am using a single servlet as a dispatcher to my page "controllers").
This technique ensures that right thing happens when I do a redirect (or forward)
from deep in my servlet code. This is in my regular servlet code (as opposed to my
JSP pages), since I don't put complex code in JSP. It would be kind of messy to use
this technique in JSP, unless you created your own JspPage class, which is not
something to do lightly.
