Protopage

AJAX is an implementation of existing web technologies that allows a web browser to communicate with a server without you having to refresh the page. Normally, when you submit a form or perform an action on a website that requires information from the server. your browser has to refresh the page, meaning you have to wait. AJAX is a way of using technologies like javascript to let let parts of web pages communicate with the server without requiring a complete page reload. You can see examples of this technology on the Google Maps website (maps.google.com) where you can scroll and zoom the map without having to refresh the page.
The Protopage site at http://www.protopage.com/ is a showcase for Ajax - you can drag boxes around the screen, set up sticky notes and links panels and change the way page looks without any delays or reloading. You can expect to see more of this technology popping up around the web as developers bring it on board.
