title: Google App Engine connection.session() error
body: <p>My App Engine logs show this.</p>
  <blockquote>
  <p>Warning: connection.session() MemoryStore is not</p>
  <p>designed for a production environment, as it will leak</p>
  <p>memory, and will not scale past a single process.</p>
  </blockquote>
  <p>Now my nodejs App can't use session. How I fix this?</p>
