Does WinCE4.2 with IE6 Support AJAX?

Hello, 

I am developing a web application and that will be mainly used in Windows CE hand sets which has WIN CE 4 with IE 6 and I just wanted to know whether AJAX and JQuery can be used in my web app or not.

I tried using UpdatePanel in my project, but, it seems to be not working. Any advice will greatly appreciated.

Thanks in advance.

Regards,
