Enable Stickiness

Since our core application uses session-based authentication, users might lose their session if the Application Load Balancer routes their subsequent requests to different backend targets. To prevent this, we need to enable Session Stickiness. This feature ensures that requests from a specific user are consistently directed to the same target for a defined period, thereby preserving their session continuity.

1. Navigate to the EC2 console and find the fcj-core-tg target group. Click on it.
