[Opensource] Forward to another jsp if session timeout

[larry hamel]

perhaps I don't understand your end goal, but be advised that expresso  (since about 4 months ago) automatically redirects a person who has (just) timed out right back to the login page, as commented in the that's-config.XML file:

        <global-forwards>
                <!-- logon is the redirection target when a user who isn't logged tries
             to access a secured page -->
                <forward name="logon" path="/Login.do"/>

if the user authenticates successfully, the user is redirected automatically to the original destination.
