title: Websocket send all clients a message in Echo Framework
body: <p>I believe that this question is almost the same with <a href="https://stackoverflow.com/questions/31532652/go-websocket-send-all-clients-a-message">this.</a></p>
  
  <p>But I use websocket in Echo framework instead of Gorilla. So I think the approach will be different.</p>
  
  <p>Echo does provide the <a href="http://labstack.com/echo/recipes/websocket" rel="nofollow noreferrer">example.</a> But it only shows how to connect with single client. When there are more than one client, the other clients don't receive message from server. </p>
  
  <p>How do I make the server broadcasts message to all connected clients?</p>
  
  <p>The accepted answer from referred link says that I have to use connection pool to broadcast messages to all connections. How can I do this in Echo framework?</p>
