Primary serverfarm with stickiness (cookie insert) goes down. Backup serverfarm kicks in with sorry servers. Primary serverfarm comes back up and returning connections still get serviced by the backup farm. The reason for this is explained in the load balancing guide.
If you want to configure a sorry server farm and you want existing connections to revert to the primary server farm after it comes back up, do not use stickiness.
To instruct the ACE to replicate HTTP-cookie sticky table entries on the standby ACE, use the replicate sticky command. Use the no form of this command to restore the behavior of the ACE to the default of not replicating HTTP-cookie sticky table entries
unfortunately that's the theory. If you have cookie inserts the clients are still stuck to the sorry servers once they have hit the sorry servers.
And my sticky group looks exactly like your first example. The documentation is kind off confusing. My interpretation of the quoted text was if your primary serverfarm is sticky your backup server farm will also be sticky no matter what you configure. That is actually why i asked.
If i use dynamic cookies from the application the clients hop from one rserver to another every 2nd or 3rd connection. The behavior of the stickiness and sorry servers then works like i want it but the stickiness itself is not consistent.
1.5a still had this behavior and i think this might be a bug.
