Description (partial)


From the command reference: we have:
(config-parammap-http) persistence-rebalance

To enable the ACE to send a GET request to the real server that was used for the last GET request,
use the persistence-rebalance command.

Usage Guidelines

With persistence rebalance enabled, when successive GET requests result in load balancing
that chooses the same policy, the ACE sends the request to the real server used for the last GET request.
This behavior prevents the ACE from load balancing every request and recreating the server-side connection
on every GET request, producing less overhead and better performance.

In fact, we send the GET request to the same real server that was used for the last GET request also when persistence rebalance is disabled.
The documentation is not reporting that persistence rebalance will make the ACE check each GET request within the same HTTP connection and rebalance the request if matching a different policy.
