  title: Amazon Elastic Load Balancing Tune Load Balancer Attributes
  summary: Resolve a load balancer by name and apply an attribute change.
  description: >-
    Resolves a load balancer by name and then modifies one of its attributes,
    such as enabling deletion protection or adjusting the idle timeout, and
    reads the load balancer back to confirm it is still active. Each step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description. The Elastic Load Balancing v2 API uses
    the AWS query protocol, so every operation is a GET whose inputs are carried
    as query parameters rather than a request body.

  summary: Find a load balancer by name and set one of its attributes.
  description: >-
    Chains describeLoadBalancers, modifyLoadBalancerAttributes, and a confirming
    describeLoadBalancers so a single attribute is changed on a named load
    balancer and the result verified.
