Dynamic Overlay- Putting an entire web site on a single DHTML file

This hack uses the POST HTTP request method to send data, communicating with the server without disrupting the user's interaction with the application. It then displays the server's response to the user.

The piece of code we will be writing, using the YUI library (my favorite), will allow users to increase/decrease their font size for a block of text, storing the font size in a cookie so that when they return to the page they don't have to modify the font size again.

Before sending data from form it is necessarily to check input date. JavaScript is ideal for that, because the all date before submitting, will be checked and by that we will save on bandwith.

But the applications which intensively using AJAX, have one problem.URL is cached by the client browser and even the server will serve new data, old data will be received by the browser.
