SAJAX PHP Resources for developing AJAX Applications
There has been quite a bit of discussion relating to AJAX
Applications which use the AJAX logic includes Google's GMail, Google Maps, just to name two of the popular ones.
SAJAX is a tool which was developed to make programming websites using a AJAX framework – also known as XMLHTTPRequest or remote scripting – as easy as possible.
I can't await what else people are going to develop using cool JavaScript and CSS hackery.
