How can I intercept/get notified about asynchronous requests in ASP.NET?
<p>I need to get notified about asynchronous requests in ASP.NET. I used the jQuery <code>.ajaxSend</code> global event but it does not trigger when using <code>UpdatePanels</code>.</p>

<p>Is there a multi-browser way to detect when a request is being made on a page?</p>
