Invalidate Question

[Gus Mus]

Is there any way to know if the session is invalidated or not ?

[Arron Zhang]

package arron;
import javax.servlet.http.HttpSessionListener;
import javax.servlet.http.HttpSessionEvent;
public class SessionCount implements HttpSessionListener {

private static int activeSessions = 0;
public static int getActiveSessions() {
return activeSessions;
}
public void sessionCreated(HttpSessionEvent e) {
activeSessions++;
}

public void sessionDestroyed(HttpSessionEvent e) {
if(activeSessions > 0) activeSessions--;
}
}

Hi,
For this u can implement the HttpSessionBindingListener Interface.There u have 2 methods valueBound and valueUnBound.
When a session is invalidated the valueUnBound is called inside which u can write some logic to hold the identification of the session invalidation.
