Document how to use HttpSessionCreatedEvent and HttpSessionDestroyedEvent

1) Create a component that implements ComponentManagerAware, for example

public class SessionApplicationListener implements ComponentManagerAware {

private ComponentManager componentManager;

@Override
public void setComponentManager(ComponentManager componentManager)

{ this.componentManager = componentManager; }

public void init()

{ componentManager.registerEventSubscriber(this); }

public void destroy()

{ HttpSessionRegistry registry = getInstance(); registry.sessions.clear(); componentManager.unregisterEventSubscriber(this); }

@Subscribe
public void onHttpSessionCreatedEvent(HttpSessionCreatedEvent event)

{ HttpSessionRegistry registry = getInstance(); registry.sessionCreated(event.getSession()); }

@Subscribe
public void onHttpSessionDestroyedEvent(HttpSessionDestroyedEvent event)

{ HttpSessionRegistry registry = getInstance(); registry.sessionDestroyed(event.getSession()); }

}

2) add spring configuration with init and destroy methods, for example

<bean id="com.onehippo.cms7.targeting.store.session.CreateListener"
class="com.onehippo.cms7.......SessionApplicationListener"
init-method="init" destroy-method="destroy"/>
