This page includes an AJAX driven form. In other words: clicking the "AJAX" button will pass 'your name' to the server, and the server will return a "hello" message. "AJAX" basically means that this page will not be reloaded in this process. This can speed up some processes. The JavaScript needed for this page, is located in the text-only-constant AJAX_JS. The page that will return the welcome message, is the file modules/ajax.asp. This is a very simple script. But you can write a much more advanced script that connects to a database, or anything you can imagine.
