Web 2.0 AJAX Loading Panel is a universal ajax loading message over a semi-transparent background, that makes the page modal and is supposed to work with any AJAX framework's onRequestStart and onRequestComplete functions. A client of mine asked me if it is possible to separate the function that creates the cool modal semi-transparent loading effect of my website (and many others, as well) from the XmlHTTPRequest function, so it could be used with other AJAX frameworks or for other purposes.
