I am using Spring and Spring Security and want to use spring-session-data-redis with RedisHttpSessionConfiguration to enable storing session IDs on redis (so clients wont loose their sessions when webapp fails and switched over to another server).
My question, what happens when Redis server is down? Will spring be able to continue to work by storing session in memory until Redis is back up? Is there a way to configure this as so?
I am using Redis on AWS ElastiCache, and Failover can take several minutes before replacement primary node is configured on the DNS.
