Inner-Browsing? XMLHTTPRequest? AJAX is the word!

I was suprised at the speed of development of technology once called as Inner-Browsing: Extending Web Browsing the Navigation Paradigm by Netscape DevEdge. I created my postXMLHTTP() JavaScript function which utilizes XMLHTTPRequest technology a couple of years ago I used it sucessfully in several PHP (including an administrative interface for my photo gallery) and ASP applications.
Now I fell behind once again. Technology evolves at great spead and powerfull standards for inner-browsing and new data excahnge formats emerged. Now the name is - AJAX. Today I found the following great link: PowerWEB LiveControls for ASP.NET. They use remotely generated script to replace the standard postback with a non-refresh callback. By the way I believe that this will be a built-in feature of ASP.NET 2.0...
Please read a small article I wrote some time ago. I placed it into my photo gallery developed in PHP/MySQL because gallery's administrative interface uses XMLHTTPRequest heavily.
