title: Is there any reason or advantage of using both session cookies and redis store for sessions
body: <p>Context</p>
  <p>In a flask app, we use a signed cookie (encoded JWT) for user data, however the amount of data has become too large to put in a cookie (specific permissions per item).</p>
  <p>Here comes redis, instead of storing the permissions in the JWT and passing it back and forth, we'll just keep it in redis.</p>
  <p>My questions are</p>
  <ol>
  <li>Is there any advantage to having signed session cookies (encoded JWT) AND using redis to store other session information</li>
  <li>Is it better to implement the session logic yourself instead of using something like <a href="https://flasksession.readthedocs.io/en/latest/" rel="nofollow noreferrer">flask-session</a></li>
  </ol>
