| [WebSockets|http://en.wikipedia.org/wiki/WebSocket] is a technology that provides full-duplex communications channels over a single TCP connection. |
| This means that once the browser establish a web socket connection to the server the server can push data back to the browser without the browser explicitly asking again and again whether there is something new for it. |
| |
| Wicket Native WebSockets modules provide functionality to integrate with the non-standard APIs provided by different web containers (like [Apache Tomcat|http://tomcat.apache.org/] and [Jetty|http://www.eclipse.org/jetty/]) and standard [JSR356|https://www.jcp.org/en/jsr/detail?id=356] implementations. |

| {warning} |
| Native WebSocket works only when both the browser and the web containers support WebSocket technology. There are no plans to add support to fallback to long-polling, streaming or any other technology that simulates two way communication. Use it only if you really know that you will run your application in an environment that supports WebSockets. |
| Currently supported web containers are Jetty 7.5+ , Tomcat 7.0.27+ and JBoss WildFly 8.0.0+. |
