It is recommended that customers set in the Site configuration parameter CREATE_HTTP_SESSION = "Y" when using ALM cluster with a load balancer.
Details of the setting: You can use this parameter if you are working with load balancing over a cluster of application servers. If the parameter is set to “Y”, ALM creates an HTTP session. This causes the load balancer to operate in sticky mode, meaning that after a request sent by a client is directed to a particular node in the cluster, all subsequent requests sent by that client are directed to the same node.
