--
-- Generates a stickiness policy with sticky session lifetimes controlled
-- by the lifetime of the browser (user-agent) or a specified expiration
-- period. This policy can be associated only with HTTP\/HTTPS listeners.
--
-- When a load balancer implements this policy, the load balancer uses a
-- special cookie to track the instance for each request. When the load
-- balancer receives a request, it first checks to see if this cookie is
-- present in the request. If so, the load balancer sends the request to
-- the application server specified in the cookie. If not, the load
-- balancer sends the request to a server that is chosen based on the
-- existing load-balancing algorithm.
--
-- A cookie is inserted into the response for binding subsequent requests
-- from the same user to that server. The validity of the cookie is based
-- on the cookie expiration time, which is specified in the policy
-- configuration.
--
-- For more information, see
