<h1>Websocket PubSub Demonstration</h1>
<p>
This page demonstrates how Mongoose could be used to implement
<a href="http://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern">
publish–subscribe pattern</a>. Open this page in several browser
windows. Each window initiates persistent
<a href="http://en.wikipedia.org/wiki/WebSocket">WebSocket</a>
connection with the server, making each browser window a websocket client.
Send messages, and see messages sent by other clients.
