That is correct. Setting the cookie expiration will not have any effect
on the browser until you actually send a response containing the new
setting (effectively deleting the cookie) -- it will be gone on a
subsequent request.
This is not really specific to Struts -- it's the way cookies work in
servlet based applications.

One option would be to use a <forward> that does a sendRedirect() instead
of a RequestDispatcher.forward(). This would cause the cookie to be
deleted, at the expense of being able to pass request attributes back to
page1.jsp again -- you'd need to use session attributes now.
