Postbacks vs Async Script Callbacks With Ajax we can refresh the data on a page without the need to refresh the whole page. This is achieved via usage of DHTML. Let’s say we have a small area on the page that needs to always have near “real time” data. Say flight times, or for a sports website, live a scorecard. This can be achieved via Ajax. With the traditional postback model, when we need to update parts of the page, we have to refresh the whole page. This involves making a request to the server, and then downloading the new page.

Last thoughts Think about the possibilities that giving users almost “live” feedback when they interact with the web application you’ve designed and develop. Forget about the traditional postback model for a brief moment and venture into the world of the rich interactive web. The biggest innovations seem to be coming from the web. The web travels at a million miles and hour. Look at the recent global disasters and how fast news about them came flying through the web. Through blogs, as well as online news websites. The web is connecting the world and making our world smaller than it already is.
