title: Use database to store session instead of Cookie with Flask
body: <p>I have a python project with Flask.</p>
  
  <p>I'm using SQL Alchemy (according to this page of the documentation : <a href="http://flask.pocoo.org/docs/0.10/patterns/sqlalche" rel="nofollow">http://flask.pocoo.org/docs/0.10/patterns/sqlalche</a>) to handle my database actions.</p>
  
  <p>I'm using <code>Flask.session</code> to store user's information (authentication status, preferences, ...)</p>
  
  <p>Default Flask's Session behaviour is to store sessions in user's cookie, and to sign this cookie with <code>secret_key</code> so users can't alter it, but they can read it.</p>
  
  <p>I don't like that my users are able to "see" session's content. Does Flask offer a built-in way to store session's content in ORM (SQLAlchemy), or do I have to implement that myself ?</p>
  
  <p>Thanks !</p>
