Yesterday, I found these 5 AJAX Anti patterns The "anti patterns" are simply what you should avoid when doing AJAX on your website. You should find them as helpful as the top ten AJAX mistakes I linked to before (or even more).
O.K.. You must have realized that the notes are from IBM, and I know my typical readers (if any) who do it the AJAX way are all using ASP.NET AJAX, but still, the notes all are concepts demonstrated with only XHTML/JavaScript code, so, it should be good for you to go with regardless of which Server side way you have to deal with.
Hint:
read these anti patterns carefully, they pretty much summerize what every AJAX developer should know, and what is discussed in many other places with way more lines and platform-specific examples.
Also, watch out for the list of "Resources" at the end of the page. They are good as well.
