I was wondering if anyone could recommend good books or other resources on designing AJAX applications ? I am looking primarily for the principles behind designing and modelling the AJAX interactions rather than specifically how to perform a particular technical function.
Naturally, if these resources use RoR or even another MVC framework for illustration, then that will be just dandy - but it's not a requirement. I have found that there are plenty of good resources from a technical Rails POV that give detailed guidance on how to implement AJAX-type behaviour, but few give a comprehensive overall view of the design principles.
Thanks for any help
