Ajax

Ajax (Asynchronous JavaScript and XML) core competency lies in getting rid of page refreshing. The Ajax driven web application has the potential to display the page right away, sans any hiccups, no refreshing or reloading is called for. Yes, Google (Google Maps), Yahoo (Flickr), and Amazon (A9 Search) has been using it, and you too can leverage on the potential of AJAX, with the backing of Rightway Solution’s Ajax expertise.

Defining Ajax

Ajax isn’t a technology. It’s really several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates:

• Standards-based presentation using XHTML and CSS;
• Dynamic display and interaction using the Document Object Model;
• Data interchange and manipulation using XML and XSLT;
• Asynchronous data retrieval using XMLHttpRequest;
• JavaScript binding everything together.

In a nutshell, it is a method to interact with the server and send data back and forth without having to refresh the whole page, which makes applications faster and saves lots of internet bandwidth.

Here is how Ajax works in comparison to classical web application.
