what was missed in this discussion, is that AJAX means Asynchronous 
JavaScript and XML - see http://en.wikipedia.org/wiki/AJAX. This 
means that you need to construct an XML document that can be GET via 
http. No problem. But if you want to send data back, you need an XML 
parser, that digs info from individual tags.

As we already use XML for get/set parameters/data, there was no need 
to implement anything in our application code to get AJAX running. 
Everything was done in JavaScript within a "static" web page, that 
was made part of a file system. We are using AJAX to paint a dynamic 
graph for several temperatures in a web page without reloading such a page.
