The EventHandler uses a number of techniques under the hood for maintaining a persistent connection. Techniques used are the standard server side push technologies such as pushlet, long polling, and multipart/x-mixed-replace. In addition, the WebSocket protocol is automatically used when the EventHandler client detects a browser that supports this new technology.
As WebSockets are gaining momentum, more companies are discovering the benefits of keeping a persistent server connection over HTTP(S) for real time device management. Our EventHandler includes WebSockets support and can be found in many Barracuda Server powered industrial products dating as far back as 2005.
