In this article, you learned how to implement session state management in an ASP.NET Core MVC application. You discovered the limitations of the default in-memory session and how to distribute your sessions using a Redis database. The distributed session allows multiple instances of your applications to share the same session data, ensuring that users' data remains consistent across different servers. By storing session data in a centralized location like Redis, you can overcome issues with concurrent access and improve scalability. You learned how to add session state management to your ASP.NET Core app, store data in the session, and retrieve it, as well as configure distributed caching with Redis to persist session data.
