HttpSessionBindingEvent

public class HttpSessionBindingEvent extends HttpSessionEvent
Events of this type are either sent to an object that implements {@link HttpSessionBindingListener} when it is bound or unbound from a session, or to a {@link HttpSessionAttributeListener} that has been configured in the deployment descriptor when any attribute is bound, unbound or replaced in a session.

The session binds the object by a call to HttpSession.setAttribute and unbinds the object by a call to HttpSession.removeAttribute.
