I ran into this very nice xmlHttpRequest tutorial, it's well written, and clearly explains how to implement this potentionally useful technique. If you read it closely, you can see some of the sources of MSIE's security issue. Here's another tutorial. That's got some pretty good information it it, and has been recently updated.

In Internet Explorer, you create the object using new ActiveXObject("Msxml2.XMLHTTP") or new ActiveXObject("Microsoft.XMLHTTP") depending on the version of MSXML installed. In Mozilla and Safari (and likely in future UA's that support it) you use new XMLHttpRequest()

This means that you need to show different script to different browsers, as what works in one, will error in another.

You can start your more in-depth readings at the W3C xmlHttpRequest page. If you can decipher the W3C speak, that is.
