PrefaceAs a next-generation WEB standard, HTML5 has a number of compelling new features, such as Canvas, local storage, multimedia programming interfaces, WebSocket, and more. The WebSocket, which has the "Web TCP" , is particularly appealing to developers. The advent of WebSocket makes it possible for the browser to provide support for sockets, providing a two-way, TCP-based connection between the browser and the server. WebSocket is a new communication protocol added by HTML5, which is support
