The Life of a User Session

Session Management is one of the many uses cases for Redis, but what do we really mean when we say Redis can be used as a session store? We’ll start with an overview of what sessions are in the context of web applications and cover some common use cases. Then we’ll look at the process of adding session management to a Node.js application using Redis as the session store. With basic session management in place, we’ll then explore options for situations where you may want to store session data after a session has ended.
