Good day, everyone!
If you forget AppFoundation, then:
-
How to most accurately by using Vaadin applies to standard notions of Session, whether or not access Session at all, or just pure Java server-side developer, then write in the style of desktop applications?
-
Since the session and Vaadin applications exist, and there is a time of its action, as you can catch the event of termination of the session to transfer the user to a login page or display a notice?
-
Maybe someone to share their methods for solving these problems, or express his opinion?
Thank you!
