<p class="main">
Ajax itself is a technique, but to use the technique
effectively one must become familiar with the philosophy
behind the technique. In other words, it is not just the use
of the technique that is important, but rather developing a
different mindset and approach to Web development that is
central.

<p class="main">
To date, I have mentioned the term ajax a number of times but
have not described the central object that makes Ajax, Ajax.
At the heart of Ajax are the xmlhttprequest object and its
Microsoft's activeX equivalent. It is this object that
allows data to be transferred asynchronously. In case you are
not clear what asynchronous means, it is the ability to
handle processes independently from other processes.
Synchronous which is the opposite of asynchronous, then means
that processes are dependent upon other processes. To
illustrate let us use a classical Web page scenario.
