This sounds exactly like the pattern I would expect if the JSP page you are forwarding
to was modified and needed to be recompiled, versus when it did not need to be
recompiled.  If that's not the issue, I would tend to look at what you are doing
inside the JSP page itself, or the beans that it utilizes.
