Using independent version conditions makes sense if you want
to use a specific feature you know is supported by a
particular version of XMLHTTP. In this instance however that
isn't applicable so we can use the version independent
method which is Microsoft.XMLHTTP. That will work on IE5
through to IE7. It also has the added benefit of keeping our
code nice and lean. And we like lean code don't we!

<p class="main">
<strong>Line 7:</strong> We check that either the
Microsoft.XMLHTTP or XMLHttpRequest objects have been created
through the usage of the previously named variable x.
</p>
<p class="main">
<strong>Line 8:</strong> The onreadystatechange event is used
to keep track of when the readystate of a document changes.
In this statement we attach the event to Microsoft.XMLHTTP or
XMLHttpRequest respectively by using the variable x.
