To summarize this request which was already partly discussed by phone:
We would like to define a custom JSP to be shown after a session timeout - but we would like to keep this JSP on server side similar to the custom error screen.
This would save us from creating a separate client JAR just for this one page. We would also have more freedom to redirect the user back to the login-page, via a button or a timer.
The handling should be similar to the custom error screen, i.e. passing the name of the JSP as a client parameter.
Thanks in advance!
