public interface AmazonElasticLoadBalancingAsync extends AmazonElasticLoadBalancing
Elastic Load Balancing is a cost-effective and easy to use web service to help you improve the availability and scalability of your application running on Amazon Elastic Cloud Compute (Amazon EC2). It makes it easy for you to distribute application loads between two or more EC2 instances. Elastic Load Balancing supports the growth in traffic of your application by enabling availability through redundancy.
This guide provides detailed information about Elastic Load Balancing actions, data types, and parameters that can be used for sending a query request. Query requests are HTTP or HTTPS requests that use the HTTP verb GET or POST and a query parameter named Action or Operation. Action is used throughout this documentation, although Operation is supported for backward compatibility with other AWS Query APIs.
For detailed information on constructing a query request using the actions, data types, and parameters mentioned in this guide, go to Using the Query API in the Elastic Load Balancing Developer Guide .
For detailed information about Elastic Load Balancing features and their associated actions, go to Using Elastic Load Balancing in the Elastic Load Balancing Developer Guide .
This reference guide is based on the current WSDL, which is available at:
Endpoints
The examples in this guide assume that your load balancers are created in the US East (Northern Virginia) region and use us-east-1 as the endpoint.
You can create your load balancers in other AWS regions. For information about regions and endpoints supported by Elastic Load Balancing, see Regions and Endpoints in the Amazon Web Services General Reference.

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 backend server 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.

Adds new instances to the load balancer.
Once the instance is registered, it starts receiving traffic and requests from the load balancer. Any instance that is not in any of the Availability Zones registered for the load balancer will be moved to the OutOfService state. It will move to the InService state when the Availability Zone is added to the load balancer.
When an instance registered with a load balancer is stopped and then restarted, the IP addresses associated with the instance changes. Elastic Load Balancing cannot recognize the new IP address, which prevents it from routing traffic to the instances. We recommend that you de-register your Amazon EC2 instances from your load balancer after you stop your instance, and then register the load balancer with your instance after you've restarted. To de-register your instances from load balancer, use DeregisterInstancesFromLoadBalancer action.
For more information, see De-register and Register Amazon EC2 Instances in the Elastic Load Balancing Developer Guide .
NOTE: In order for this call to be successful, you must provide the same account credentials as those that were used to create the load balancer.
