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.

in the Classic Load Balancers Guide.
