I would like to know that with Cookie based session persistence, does the cookie hash value remain the same throughout the lifetime of server farm. Because, I believe the hash value is calculated out of serverfarm + rserver + port which is not expected to change.
Please suggest whether the cookie value ever changes for a specific serverfarm.
Cookie value will be unique for each rserver in Serverfarm.
The ACE creates a unique static entry (based off of a hash of the port, rserver name, and serverfarm name)in sticky database for every rserver in the serverfarm. This value will never change for a "specific real server" in a server farm.
Another recent change in the ACE code let you define a string for each rserver (instead of using hash value). For more info read my post at
