Interface javax.servlet.http.HttpSessionBindingListener

public interface HttpSessionBindingListener
extends EventListener
Objects implement this interface so that they can be notified when they are being bound or unbound from a HttpSession. When a binding occurs (using HttpSession.putValue) HttpSessionBindingEvent communicates the event and identifies the session into which the object is bound.

Similarly, when an unbinding occurs (using HttpSession.removeValue) HttpSessionBindingEvent communicates the event and identifies the session from which the object is unbound.
