The document provides a history of web application development from 1991 to the present. It begins with Tim Berners-Lee creating the first webpage in 1991 using HTML. In the mid-1990s, web development began as browsers and servers evolved. The late 1990s saw the commercialization of the web and technologies like Java applets and Flash. AJAX was coined in 2005 and allowed asynchronous javascript requests. Current technologies include HTML5 features like video, audio, and canvas. The document also outlines approaches to web development like scripting and frameworks. Finally, it provides example commands to start a sample Django application using Python and a database.
