title: Can websocket client connect to the websocket server from different ports other than 80/443
body: <p>I am a novice on Websocket programming, but my latest project required to deploy a WebSocket Server on Ubuntu Linux Server. I have read some from the internet, and know - </p>
  
  <ol>
  <li>The websocket client will connect to the server by port 80/443, and its protocol identifier is ws/wss accordingly. <a href="http://www.websocket.org/aboutwebsocket.html" rel="noreferrer">http://www.websocket.org/aboutwebsocket.html</a></li>
  <li>The Apache/Nginx web server commonly will listen to 80/443 at server-side, so we have to config Apache/Nginx to support ws/wss protocol, better transmit the connection to a websocket server like a proxy do.</li>
  <li>There are some websocket server add-on for Apache, also I know Nginx 1.3+ support websocket protocol natively, and it's fine to config it as well working with a websocket server.</li>
  </ol>
  
  <p>Based on what I knew, I think I can deploy Apache/Nginx and a Websocket Server together through 80/443. I am wondering, if we can just use the websocket server indepdently? I think if we can write a websocket client connecting to the server from other ports , then we can do it.</p>
  
  <p>So can we write a websocket client to connect the server from different port ? </p>
