title: Send a GET-request after app starts listening
body: <p>I know this is unorthodox, but I was wondering if there's a way to use a redirect inside of the app.listen, something like this: </p>
  
  <pre><code>app.listen(app.get('port'), function () {
    //res.redirect("some url")
  })
  </code></pre>
  
  <p>The fact is I need to launch a <strong>GET request</strong> after the app is on listen mode, after some research I've found it could be done with a redirect; clearly, I don't have a routing and a response object res to afford it.</p>
  
  <p>How could I achieve this? </p>
