Step by Step to AJAX - Ajax's Model of Interaction (Page 2 of 5 )
The figure shown next is derived from Garret's article on Ajax, redrawn to render it horizontally. The figure shows both the prior art (classic interaction) as well as the AJAX embodiment. In the classic version, the client sends an HTTP(S) request to the server, the server checks to see whether any server side processing is to be carried out, processes the server related instructions and sends back the html with CSS, if it is defined. There is a synchronicity between client request and server response.
