*
- * <p><b><u>Router</u></b></p>
+ * Ext.Direct utilizes a "router" on the server to direct requests from the client to the appropriate server-side
+ * method. Because the Ext.Direct API is completely platform-agnostic, you could completely swap out a Java based server
+ * solution and replace it with one that uses C# without changing the client side JavaScript at all.

+ * # Server side events
*
- * <p><b><u>Server side events</u></b></p>
+ * Custom events from the server may be handled by the client by adding listeners, for example:
+ *
+ * {"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
+ *
+ * // add a handler for a 'message' event sent by the server
+ * Ext.direct.Manager.on('message', function(e){
+ * out.append(String.format('<p><i>{0}</i></p>', e.data));
+ * out.el.scrollTo('t', 100000, true);
+ * });
