title: Node.js: ECONNREFUSED on Port 80
body: <p>I've written a web-server using Node.js.
  When I tried to test my server with the tester I've written for it, I succeed only if the port I'm using for the server is not 80.
  I've checked on netstat, and no other application is using port 80.
  The error I'm getting on the console is:</p>
  
  <pre><code>Error: connect ECONNREFUSED
    at errnoException (net.js:640:11)
    at Object.afterConnect [as oncomplete] (net.js:631:18)
  </code></pre>
  
  <p>What can be done in this case?</p>
