Helix Core Server Administrator Guide: Multi-Site Deployment (2019.2)

Configuring a forwarding replica

A forwarding replica offers a blend of the functionality of the Helix Proxy with the improved performance of a replica.

If you are auditing server activity, each of your forwarding replica servers must have its own P4AUDIT log configured.

Note

An edge server between a forwarding replica and a commit server is not supported.
