// 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 [Duration-Based Session Stickiness] in the Classic Load Balancers Guide.
