[2005] XML HTTP Request Object?

How do I use the XML HTTP Request Object in ASP.NET 2.0 ?

Can I use it without Ajax?

Yes. you can use the XML HTTP Request without Ajax.

Pls Refer this MSDN

I think you mean HttpWebRequest. The XmlHttpRequest IS AJAX. AJAX is just a fancy name for code involving XmlHttpRequest; XmlHttpRequest is a JavaScript thing.

So, what I mean is:

In your codebehind, you'd use HttpWebRequest and HttpWebResponse.
In your client-side code, you'd use XmlHttpRequest.
