title: Primefaces Push: WebSocket to Long-Polling unexpected
body: <p>I have a web application based on Prime Push with below detail</p>
  
  <ol>
  <li><blockquote>
    <p>= Tomcat 7.0x75</p>
  </blockquote></li>
  <li><blockquote>
    <p>= Primfaces 6.x</p>
  </blockquote></li>
  <li>Amazon EC2</li>
  </ol>
  
  <p>Currently I do see the Long-Polling being used instead of Web-Socket. Do you know what reason behind why Web-Socket is not used and downgrade to Long-Polling?</p>
  
  <p>Note: It was used to work but now it stopped working which I can't find out the root cause.</p>
  
  <p>Please let me know if you need any information.</p>
  
  <p>Thanks,
  Nghia</p>
