Automatic redirection to Expiry Page once the session timeout is reached - Possible options

[mfs]

Guys,

I wanted to add this feature in my application, where once the session-timeout period is reached, the user is automatically redirected to the session-expiry page, like the way you might have seen in various banking sites.

In order to achieve the above the first component which came to my mind was AbstractAjaxTimerBehavior, on which i set the to event-invocation-time to => "session-timeout_period + 1 mill-sec (or 1 sec)", where when the ajax-event is invoked (once the timeout is reached), the wicket framework would automatically redirect the user to the session-expiry page.

The problem is that since my application pages has various ajax-components in it and not every request results in the whole page being rendered, i am not sure which component to attach this ajaxTimerBehavior with, such that the AjaxTimerBehavior's timer is updated accordingly with every ajax-request (as well).

Can anyone suggest as to what would be the right way to go with this, or an alternate solution to the above requirement..

Thanks in advance and Regards,

Farhan.

Another point worth mentioning in the solution i discussed in my earlier post is that i would want the ajax timer-based event (with the help of ajaxTimerbehavior) to be invoked ONLY when the session-timeout period has reached, as otherwise the ajax-event would unnecessarily result in the extension of the session-timeout period of the app, without any user event, something i certainly don't want.

It is the above reason, why i mentioned in my earlier post, that i would want to update the timer period on every ajax request, as otherwise the ajax-event would be invoked based on the time-set on AjaxTimerBehavior component when the page was first rendered AND not based on the actual session-timeout period, which would have changed, had there been any ajax-based communication after the page was first rendered.

Hope it make sense..

Thanks

Maybe you can create your custom RequestCycle and do something
like this

@Override public void detach() {
    try {
        AjaxRequestTarget target = AjaxRequestTarget.get();
        target.addComponent(Mysession.get().getSessionExpiryComponent());
    } finally {
        super.detach();
    }
}

I'm not sure if it would work, but in general RequestCycle can
be used for making hooks in every request processing.

Best wishes,
Timo

Timo,
Thanks for the followup, i will give this a try, though i doubt it work given my understanding that components rendering are linked with an html page, and in this case i am not sure how would the request-cycle would bind the target component to one..

Thanks

Ajax requests all also processed within RequestCycles.
