AJAX

Thsi is a beginning of a long serie on the technologies which make AJAX. The basic principle of AJAX is making Web pages more responsive by allowing more complex interaction with the servers without requiring the reloading of a page. The name AJAX means asynchronous Javascript with XML. Two main important applications:

1. load pages more quickly through an asynchron loading of the page(i.e the whole page is not loaded immediately).
2. depending on the actions of the user, appropriate data can be loaded without requiring the reloading of the page

Most applications require for this task the use of XMLHttpRequest Objects.
