INTRODUCTION


AJAX is basically an interaction between the user and the server. When user inputs something on the webpage, the information travels to the server. The server receives this input, analyses the input and then send backs "some" information to the webpage. The webpage content is updated dynamically based upon this input. Google's auto suggestion and many other similar interactive pages are based upon AJAX.
