Creating Web Applications with HTML5 WebSockets
| WebSockets enables the real-time web where the information is available to the user the moment it is published. WebSockets are standard based, Interoperable across browsers and very simple to use. We got the WebSockets support everywhere it is available on browsers, windows run time, WCF, ASP, IIS etc. This post gives you the basic idea about WebSockets and the technicalities behind this concept. |  |
There is a deep desire for speed to get the information as quickly as possible.
Typical examples where user wants to see the information in real time
- Stock Market data
- Live Scores
- Airline Location
- Twitter Search Results
- Interactive games
The Problem
HTTP is a state less protocol where server can communicate with client only once per request received. Real time web needs asynchronous communication with client.
