xmlHttpRequest

I am always fascinated with google! How did they know about ajax and stuff ahead and came up with Google suggest kind of feature..Ajax is cool. did you know, even Gmail is ajax based.. but, have you ever thought about the architecture behind ajax? we have so many toolkits nowadays which is ajax enabled hiding what is going on behind...but its always good to understand architecture..

I am not going to explain it all as this article does. the crux is this object xmlHttpRequest.
Have fun reading this article. Thanks to the author for a wonderful explanation.
