When a user has an associated HttpSession object and then want to log out

  • 0

When a user has an associated HttpSession object and then want to “log out” of the application you would invalidate that HttpSession which in turn would remove it from the map that the ServletContext keep of all sessions. But this only removes it on the server side, what happens on the client side? Does the user still keep keep the cookie with the session ID which now no longer has a corresponding session object on the server and keeps sending this to the webserver? And what happens when the user wants to login again after logging out?

    I imagine the sessionId cookie will still be kept, but since this sessionId will not match any session object in the server’s memory, it will be discarded by the server next time user tries to login again. On the server side it will be quite transparent, request.getSession() will return a new session object automatically.
