I'm exploring using Redis for session storage with Adobe CF 2021, with the goal of being able to failover to a backup CF server while persisting user session data. I would want Redis to have failover capabilities as well, but it looks like CF admin only accepts a single IP for the Redis server. I tried having it connect to a Redis Sentinel, but that doesn't look like it's supported. What's the best way to connect CF to Redis for session storage, and not have a single point of failure?
