Unload works in modern browsers, but for example you cant launch an alert. See: http://bugs.jquery.com/ticket/10509

Also if you want to use $.get or $.post in unload, is better that you use $.ajax with async=false.

Ex:

$(window).unload(function() {
            $.ajax({
              url: '/some_url.htm',
              async: false
            });
    });
