Currently in a redundant gateway configuration with Perspective projects using Ignition IdP's, on failover from Primary to Backup gateway, all Perspective sessions are forced to re-authenticate with the Backup gateway.

This is a huge regression from the way it was handled in Vision, where the client could stay logged in and on the same page they were (once all data connections were re-established).

It seems the reason for this is that the Backup gateway doesn't have any way to "trust" all these new sessions that begin talking to it.

Surely a unique fingerprint or something about all active and authenticated sessions can be passed along to the Backup during standard redundancy status syncing, to get around this issue?
