Martin Grigorov reopened WICKET-4444:
-------------------------------------
> Add a callback to the Session which is called when the HttpSession is
> invalidated
> ---------------------------------------------------------------------------------
>
> Key: WICKET-4444
> URL: https://issues.apache.org/jira/browse/WICKET-4444
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 6.0.0-beta1
> Reporter: Martin Grigorov
> Assignee: Martin Grigorov
> Attachments: WICKET-4444.patch
>
>
> Currently the only notification that a user session has gone is
> org.apache.wicket.Application#sessionUnbound(String) which gives only the
> http session id as context.
> With the proposed change it will be possible to have an explicit callback
> method in o.a.w.Session itself. It will be called after explicit usage of
> Session#invalidate(Now)() or http session expiration due to inactivity.
> See the proposed patch.
> One "problem" is that now the http session attribute that holds the instance
> of SessionBindingListener will keep a reference to the Wicket session, but I
> think this should not cause bigger memory footprint because the same Session
> instance is already kept in another attribute in the http session, so the
> serialization process will just link the second to the first.
