Our configuration is we have a single load balancer per datacentre that have their configurations kept in-sync (manually).
We often shift traffic for these various *.company.com hosts like mentioned above, with cookie persistence, this creates issues with the APM module when it receives a cookie from another F5 load balancer.
What seems to happen is a redirect to /my.logout.php3?errorcode=20 with message:
Invalid Session ID. Your session may have expired.
Any ideas here of what we can do? Perhaps replicate the APM session database somehow?
