The Javascript strikes back

Today, I read some interesting things about XmlHttpRequest and AJAX (Asynchronous JavaScript with XmlHttpRequest) (not this AJAX ;)

Here are some good links.
* XmlHttpRequest on xml.com
* AJAX in wikipedia
* Examples using XmlHttpRequest
* W3C DOM Level 3 with features similar to XmlHttpRequest
* Microsoft XmlHttpRequest documentation

And some projects.
* the sarrisa library
* the XHConn library
* the Sajax project

XmlHttpRequest was introduced in IE 5.0, but now that the architecture has a name (AJAX), it seems that everybody is talking about that.
