title: Is it possible to send a message to all active WebSocket connections? Using either node.js or python tornado websockets
body: <p>I'm experimenting with building a websocket's based application.</p>
  
  <p>I am wondering whether it's possible to send a message to all active connections as they are persistant.</p>
  
  <p>Say I'm running a live auction site and I have multiple users watching the auction page, each of them is connected via sockets to my server. Now let's say one user raises the bid.  I want to send a message to all connected clients. Easiest way is to have the clients poll the server via socket every second, but I think the idea of websockets is to have true bi-directional communication.</p>
  
  <p>How can this be done?</p>
  
  <p>thanks in advance,</p>
