title: Meteor.js deploy to "example.com" or "www.example.com"?
body: <p>I recently deployed a meteor app using the following command:</p>
  <pre><code>$ meteor deploy example.com
  </code></pre>
  <p>and later (thinking that it was the same) using the following:</p>
  <pre><code>$ meteor deploy www.example.com
  </code></pre>
  <p>It end up serving two different versions of the app, one hosted in <code>example.com</code> and other hosted in <code>www.example.com</code>.</p>
  <p>Can I revert one of the deploys? Which one should I revert?</p>
  <p>If not, what kind of configs should I set on my domain provider?</p>
