HttpSessionListener

Interface HttpSessionListener

All Superinterfaces:
java.util.EventListener

Implementations of this interface are invoked at their sessionCreated(javax.servlet.http.HttpSessionEvent) method in the order in which they have been declared, and at their sessionDestroyed(javax.servlet.http.HttpSessionEvent) method in reverse order.

Servlet 2.3
