-- | Generates a stickiness policy with sticky session lifetimes that follow that
-- of an application-generated cookie. This policy can be associated only with
-- HTTP/HTTPS listeners.
--
-- This policy is similar to the policy created by 'CreateLBCookieStickinessPolicy', except that the lifetime of the special Elastic Load Balancing cookie
-- follows the lifetime of the application-generated cookie specified in the
-- policy configuration. The load balancer only inserts a new stickiness cookie
-- when the application response includes a new application cookie.
--
-- If the application cookie is explicitly removed or expires, the session
-- stops being sticky until a new application cookie is issued.
--
-- An application client must receive and send two cookies: the
-- application-generated cookie and the special Elastic Load Balancing cookie
-- named 'AWSELB'. This is the default behavior for many common web browsers.  For
-- more information, see <http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/US_StickySessions.html#US_EnableStickySessionsAppCookies Enabling Application-Controlled Session Stickiness> in
-- the /Elastic Load Balancing Developer Guide/.
