  Elastic Load Balancing

  A load balancer can distribute incoming traffic across your EC2 instances.

  This enables you to increase the availability of your application. The load
  balancer also monitors the health of its registered instances and ensures that
  it routes traffic only to healthy instances. You configure your load balancer to
  accept incoming traffic by specifying one or more listeners, which are
  configured with a protocol and port number for connections from clients to the
  load balancer and a protocol and port number for connections from the load
  balancer to the instances.

  Elastic Load Balancing supports three types of load balancers: Application Load
  Balancers, Network Load Balancers, and Classic Load Balancers. You can select a
  load balancer based on your application needs. For more information, see the
  [Elastic Load Balancing User Guide](https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/).

  This reference covers the 2012-06-01 API, which supports Classic Load Balancers.
  The 2015-12-01 API supports Application Load Balancers and Network Load
  Balancers.

  To get started, create a load balancer with one or more listeners using
  `CreateLoadBalancer`. Register your instances with the load balancer using
  `RegisterInstancesWithLoadBalancer`.

  All Elastic Load Balancing operations are *idempotent*, which means that they
  complete at most one time. If you repeat an operation, it succeeds with a 200 OK
  response code.

  Generates a stickiness policy with sticky session lifetimes that follow that of

  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, `AWSELB`, 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.

  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.
