PusherWebSockets is an extension with a basic implementation of the websocket API from Pusher.
You can send a message from a server to all connected clients.
On the clients the message will be received in an OnNotify action, which means that you can build your own client-functionality around the message.
You can show the message in an alert or feedback message block.
You can also trigger one or more actions based on the value of message (for instance refresh a (part of a) screen, redirect to another page or logout).
