Yes, and the same happens for AbstractHttpSessionStore#onUnbind
What that class does on #bind is this:
// register an unbinding listener for cleaning up
String applicationKey = application.getApplicationKey();
httpSession.setAttribute("Wicket:SessionUnbindingListener-" +
applicationKey,
new SessionBindingListener(applicationKey,
httpSession.getId()));
where SessionBindingListener is this:
/**
* Reacts on unbinding from the session by cleaning up the session
related
* application data.
*/
protected static final class SessionBindingListener
implements
HttpSessionBindingListener,
Serializable
{
private static final long serialVersionUID = 1L;
/** Session id. */
private final String sessionId;
/** The unique key of the application within this web
application. */
private final String applicationKey;
/** Whether it is already unbound. */
private boolean unbound = false;
/**
* Construct.
*
* @param applicationKey
* The unique key of the application within this web
* application
* @param sessionId
* The session's id
*/
public SessionBindingListener(String applicationKey, String
sessionId)
{
this.applicationKey = applicationKey;
this.sessionId = sessionId;
}
/**
* @see
javax.servlet.http.HttpSessionBindingListener#valueBound(javax.servlet.http.HttpSessionBindingEvent)
*/
public void valueBound(HttpSessionBindingEvent evg)
{
}
/**
* @see
javax.servlet.http.HttpSessionBindingListener#valueUnbound(javax.servlet.http.HttpSessionBindingEvent)
*/
public void valueUnbound(HttpSessionBindingEvent evt)
{
if (!unbound)
{
unbound = true;
Application application =
Application.get(applicationKey);
if (application != null)
{
application.getSessionStore().unbind(sessionId);
}
}
}
}
