-- | Session stickiness provides the ability to define multiple requests from
-- a single viewer as a single session. This prevents the potentially
-- inconsistent experience of sending some of a given user\'s requests to
-- your staging distribution, while others are sent to your primary
-- distribution. Define the session duration using TTL values.
