 The following configuration values exist for Flask-Session.  Flask-Session loads these values from your Flask application config, so you should configure
 your app first before you pass it to Flask-Session.  Note that these values cannot be modified after the ``init_app`` was applyed so make sure to not modify them at runtime.
 
-We are not supplying something like ``SESSION_REDIS_HOST`` and ``SESSION_REDIS_PORT``, if you want to use the ``RedisSessionInterface``, you should configure ``SESSION_REDIS`` to your own ``redis.Redis`` instance. This gives you more flexibility, like maybe you want to use the same ``redis.Redis`` instance for cache purpose too, then you do not need to keep two ``redis.Redis`` instance in the same process.

 The following configuration values are builtin configuration values within Flask itself that are related to session.  **They are all understood by
 Flask-Session, for example, you should use PERMANENT_SESSION_LIFETIME to control your session lifetime.**
