I'm looking for a book in or around 100 pages (maybe 200) that will explain Ajax (from a high level) and talk about its' principles & patterns... Something like Steven Krug's "Don't Make Me Think"... Suggestions?
The book is for my co-workers who do not have years of experience with Ajax. They do have experience in web application development, PHP, MySQL, and generally a good understanding of HTTP.
I appreciate your wisdom(s)!
