HTML5 Server-Push Technologies, Part 1. The upcoming HTML5 specification includes a lot of powerful and exiting features which turn web browsers into a fully capable rich internet application (RIA) client platform. This article takes a deeper look into two new HTML5 communication standards, Server-Sent Events and WebSockets. These new standards have the potential to become the dominant Server-push technologies for helping developers to write real-time web applications. 1. The evolution of the web Since its beginning in the 1990s, the World Wide Web has grown rapidly and became more and more dynamic. While the first generation of web pages were static documents, later generations of web sites have been enriched by dynamic elements, followed ultimately by the development of highly-interactive browser-based rich internet applications.
The Hypertext Transfer Protocol (HTTP) was designed in the early days of the internet to transport information entities such as web pages or multimedia files between clients and servers. Listing 1. Server-Sent Events. Abstract This specification defines an API for opening an HTTP connection for receiving push notifications from a server in the form of DOM events. The API is designed such that it can be extended to work with other push notification schemes such as Push SMS.

HTML5 Demos. HTML5 — Edition for Web Developers. Submit Site | HTML5 Websites. HTML5 Tutorial -- Quick Introduction to HTML 5. In June 2013, Coreservlets.com will be hosting a live HTML5 training course in Maryland, developed and taught by David Geary. David is the author of Core HTML5 Canvas (as well as eight best-selling Java texts), is a three-time Java Rock Star at Java One, and has spoken and taught all over the world. This is the beginning of what I hope will become a more extensive tutorial on HTML5. Although I hope in the long term to cover some of the advanced HTML5 topics that will be supported in upcoming browser releases, the main reason I put the tutorial together was to answer two questions of short-term importance: What is the basic structure of an HTML5 document, and will this structure work in older browsers that know nothing of HTML5?
What new input types (sliders, color pickers, etc.) are available in HTML5, how do I use them, what browsers support them, and how can I use them in a way that will avoid problems in older browsers that know nothing of HTML5?
