<p>Is there any possibility how to send AJAX after close the browser window? </p>

<p>I have a browser game with movement in JavaScript (jQuery) and if I send Ajax after each movement it would be difficult for the server. So I want to send one AJAX when user close the window (or bookmark). 
It must be functional in all modern browsers.</p>

<p>Thank you for answers</p>
