ColdFusion 2016 Redis Session Storage with SSL and password, Elasticache

Report · May 26, 2020

I'm working towards using Redis to store ColdFusion sessions in an ElastiCache instance.

ElastiCache has encryption options:

Encryption at Rest (This works easily. It is transparent to Redis Connections)
Encryption in Transit
- Redis Auth

Ideally both of the last two options should be enabled. Redis Auth can only be enabled when Encryption in Transit is enabled.

When Encryption in Transit is enabled, connection timouts occur while verifying the Redis connections.

Redis Connection Verification Failed. java.net.SocketTimeoutException: Read timed out

For this connection, I'm using a plain hostname. I am not modifying the address to create different url in any way.

I've seen some articles about the redis url scheme and using
redis:// for plain text connections

rediss:// for SSL connections.
However, when either of these are configured in the coldfusion administrator page, the connection verification throws an error.
Redis Connection Verification Failed. java.net.UnknownHostException

How can I enable SSL in the connection to Redis for the session storage?

What about using th IP address instead of the hostname? I would try it together with the standard Redis port, 6379.
