title: Default document in Google App Engine
body: <p>Is it possible to specify the equivalent of a default document for directories in Google App Engine so that navigating to that directory automatically redirects to its index.html for example, if it contains one?</p>
  
  <p>If I have this in my app.yaml:</p>
  
  <pre><code>- url: /demos
    static_dir: demos
  </code></pre>
  
  <p>and the demos directory contains an index.html page, how can I tell App Engine to automatically redirect to that page?</p>
