Method Detail
-
setEndpoint
void setEndpoint(String endpoint)
Overrides the default endpoint for this client ("elasticloadbalancing.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.Callers can pass in just the endpoint (ex: "elasticloadbalancing.amazonaws.com") or a full URL, including the protocol (ex: "elasticloadbalancing.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's
ClientConfiguration
will be used, which by default is HTTPS.For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
- Parameters:
endpoint
- The endpoint (ex: "elasticloadbalancing.amazonaws.com") or a full URL, including the protocol (ex: "elasticloadbalancing.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
-
setRegion
void setRegion(Region region)
An alternative tosetEndpoint(String)
, sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the
ClientConfiguration
supplied at construction.This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
- Parameters:
region
- The region this client will communicate with. SeeRegion.getRegion(com.amazonaws.regions.Regions)
for accessing a given region. Must not be null and must be a region where the service is available.- See Also:
Region.getRegion(com.amazonaws.regions.Regions)
,Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration)
,Region.isServiceSupported(String)
-

createAppCookieStickinessPolicy
CreateAppCookieStickinessPolicyResult createAppCookieStickinessPolicy(CreateAppCookieStickinessPolicyRequest createAppCookieStickinessPolicyRequest)
Generates a stickiness policy with sticky session lifetimes that follow that of an application-generated cookie. 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.
For more information, see Application-Controlled Session Stickiness in the Elastic Load Balancing Developer Guide.

createAppCookieStickinessPolicyRequest
-- Returns:
- Result of the CreateAppCookieStickinessPolicy operation returned by the service.
- Throws:
LoadBalancerNotFoundException
- The specified load balancer does not exist.DuplicatePolicyNameException

-
createLBCookieStickinessPolicy
CreateLBCookieStickinessPolicyResult createLBCookieStickinessPolicy(CreateLBCookieStickinessPolicyRequest createLBCookieStickinessPolicyRequest)
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 back-end 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.
For more information, see Duration-Based Session Stickiness in the Elastic Load Balancing Developer Guide.
- Parameters:

-
registerInstancesWithLoadBalancer
RegisterInstancesWithLoadBalancerResult registerInstancesWithLoadBalancer(RegisterInstancesWithLoadBalancerRequest registerInstancesWithLoadBalancerRequest)
Adds the specified instances to the specified load balancer.
The instance must be a running instance in the same network as the load balancer (EC2-Classic or the same VPC). If you have EC2-Classic instances and a load balancer in a VPC with ClassicLink enabled, you can link the EC2-Classic instances to that VPC and then register the linked EC2-Classic instances with the load balancer in the VPC.
Note that
RegisterInstanceWithLoadBalancer
completes when the request has been registered. Instance registration takes a little time to complete. To check the state of the registered instances, use DescribeLoadBalancers or DescribeInstanceHealth.After the instance is registered, it starts receiving traffic and requests from the load balancer. Any instance that is not in one of the Availability Zones registered for the load balancer is moved to the
OutOfService
state. If an Availability Zone is added to the load balancer later, any instances registered with the load balancer move to theInService
state.If you stop an instance registered with a load balancer and then start it, 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 use the following sequence: stop the instance, deregister the instance, start the instance, and then register the instance. To deregister instances from a load balancer, use DeregisterInstancesFromLoadBalancer.
For more information, see Deregister and Register EC2 Instances in the Elastic Load Balancing Developer Guide.
- Parameters:
registerInstancesWithLoadBalancerRequest
-- Returns:
- Result of the RegisterInstancesWithLoadBalancer operation returned by the service.
- Throws:
