 * Principe : remplacement d'un element html nomme par un contenu dynamique (appel serveur en tache de fond)
 * See also: <http://developer.apple.com/internet/webcontent/xmlhttpreq.html>
 * Note :
It is essential that the data returned from the server be sent with a Content-Type set to text/xml.
Content that is sent as text/plain or text/html is accepted by the instance of the request object
however it will only be available for use via the responseText property.
 * Usage :
With all the AJAX excitement, it's worth pointing out a simple technique
I call JAH - which can be Just Async HTML, or Javascript Async HTML to taste.

This works on the microformat principle that XHTML is XML, but with the
added advantage that Javascript already knows how to handle XHTML DOM's
so no xml parsing is required.

You just include <script type="text/javascript" language="javascript1.3" src="jah.js"></script>
in the <head> and then link to dynamic pages with
<a href="javascript:jah('kevin.html','target');">kevin</a>
where target is the id of the HTML element you want to replace.
