You are having trouble maintaining session states on some of your applications that are using an Elastic Load Balancer(ELB). There does not seem to be an even distribution of sessions across your ELB. Which of the following is the recommended method by AWS to try and rectify the issues to overcome this problem that you are having? Choose the correct option from the below:
A. Use ElastiCache, which is a web service that makes it easy to set up, manage, and scale a distributed in-memory cache environment in the cloud.
B. Use a special cookie to track the instance for each request to each listener. When the load balancer receives a request, it will then check to see if this cookie is present in the request.
C. Use the sticky session feature (also known as session affinity), which enables the load balancer to bind a user's session to a specific instance. This ensures that all requests from the user during the session are sent to the same instance.
D. If your application does not have its own session cookie, then you can configure Elastic Load Balancing to create a session cookie by specifying your own stickiness duration.
