Does REST web-services allow any AJAX functionality for Rails applications?

I ask as I was wondering REST can post and invoke XML requests and supports HTTP protocol and this is a web-service its highly probable it can give AJAX like functionality to a RAILS application. If this is true, my question is HOW?

AJAX is entirely independent of REST; a RESTful application can be made to use AJAX or not, as your needs indicate. Rails 2 has added some features that make adding this sort of dynamic behavior to your application even easier than it has been in the past, however. Chapter 2 of my book deals with this in part, and you see hints of it in some of the projects that follow.

Essentially, the idea is that an AJAX request is just a standard HTTP request with a specific format. Rails allows you to respond differently to different request formats automatically, which means that you can layer a RESTful web service on top of a standard, HTML-based web application very easily.
I agree. Here's the link:
