Explanation
When users are frequently prompted to log in, it might indicate that their requests are being directed to different instances, leading to a loss of session state. Enabling sticky sessions (session affinity) ensures that requests from the same client are consistently directed to the same EC2 instance. This is important for applications that rely on maintaining session state.
