title: Subdomain on Cloud 9 Rails App
body: <p>I just started using Cloud 9 with my app. Part of my app has an API that is accessed through a subdomain - api.domain. I was curious if anyone was able to access a subdomain through the application C9 creates when running your rails server?</p>
  
  <pre><code>rails s -p $PORT -b $IP
  </code></pre>
  
  <p>Thanks in advance!</p>
