discussion of some of synchronous communication using the POST method instead

This tutorial starts with an Introduction followed by a short discussion on
AJAX merits and demerits. The following section is about Implementation,
where most of issues concerned have been handled. It's followed by a complete
running example code, which can be simply taken and run on local server. T
