// | What is this nonsense?? (07/09/04)                                   |
// +----------------------------------------------------------------------+
// | This is a script that, by using XMLHttpRequest javascript objects    |
// | you can quickly add some very click live interactive feed back to    |
// | your pages that reuire server side interaction.                      |
// |                                                                      |
// | For instance, you use this to emulate a "live searching" feature     |
// | wherein users type in key phrases, and once they have stopped typing |
// | the script will automatically search and retrive *without* a page    |
// | reload.
// |                                                                      |
// | In another instance, I use this to product live comments by passing  |
// | the text to a Textile class that parses it to valid HTML. After      |
// | parsing, the html is returned and displayed on the page as the       |
// | user types.                                                          |
