1. StartFor distributed cache, the usual session processing is a user corresponding to a distributed machine, if the machine is hanging in the middle or can not handle the user session, the user's session will be lost, unpredictable errors occur. Such as:If you use Redis's distributed cache, you can avoid the above situation. Because the session is stored in Redis
