delay closing of a browser window

[dolittle]

Hi,

I have an event listener:

Ext.EventManager.on(window, 'beforeunload', terminateSession);

In the function teminateSession I`m sending an ajax request to the server to tell him that the session should be closed. I need to:
- delay the closing of the window until I get a response from the server.
- or for a few seconds so I`ll know the server probably got my ajax request.

Is it possible?

Thanks

This will probably just be fire and forget, but it should get enough time to send a small "logout" request.

We do this in our legacy app which maintains a stateful session from the webserver back to the legacy backend code which maintains a unix process. We try to clear it up as soon as the use navigates away of closes the window.

With this in place, the window would not close/back/forward until you get a response:

var terminateSession = function(){

 var response = Ext.lib.Ajax.request('PUT','logout.php', null,null,{async:false});
 
 
 //if you wanted to prevent the action just:
 // return false;
 
}

It's not an event you can cancel.
