Overview
In this web-based project, we use Callback technology to create a simple vehicle tracking application and show how to interact between the client side and server side. Almost all of the functionality is implemented by using client-side JavaScript. Therefore we don't need to post back to the server side every time, and the server side doesn't need to send the entire page to the client side. You can see how Callback technology minimizes the need to transfer data over the Internet, which enhances the user experience.
