This 15// policy can be associated only with HTTP/HTTPS listeners. When a load balancer 16// implements this policy, the load balancer uses a special cookie to track the 17// instance for each request. When the load balancer receives a request, it first 18// checks to see if this cookie is present in the request. If so, the load balancer 19// sends the request to the application server specified in the cookie. If not, the 20// load balancer sends the request to a server that is chosen based on the existing 21// load-balancing algorithm. A cookie is inserted into the response for binding 22// subsequent requests from the same user to that server. The validity of the 23// cookie is based on the cookie expiration time, which is specified in the policy 24// configuration.
