sessionAffinityTtl

Time, in seconds, until this load balancer's session affinity cookie expires after being created. This parameter is ignored unless a supported session affinity policy is set. The current default of 82800 (23 hours) will be used unless session_affinity_ttl is explicitly set. Once the expiry time has been reached, subsequent requests may get sent to a different origin server. Valid values are between 1800 and 604800.
