title: Enabling SSL on Flask + Google App Engine
body: <p>I'm trying to implement some Google APIs in my Flask/Google App Engine web app. </p>
  
  <p>I'm currently stuck on the authentication part as oauth2 redirect URI requires the connection to be secure and I cannot do that with Flask since it's the GAE environment that starts my flask app and I cannot do as suggested from the Flask documentation <a href="http://flask.pocoo.org/snippets/111/" rel="noreferrer">here</a></p>
  
  <p>Do you know how to enforce HTTPS on a Flask application ran by Google App Engine? </p>
