title: Listen additional port Microsoft Azure Nodejs
body: <p>I'm running nodejs application (Azure Web App) on port process.env.PORT (1337), default port on Microsoft Azure.
  Also I need to listen additional port for websocket. On my local I'm using 8000, but seems, that it's closed on Azure.</p>
  
  <p>Are there any additional ports, that I can listen and is it actually possible at all?</p>
