# How does Redis caching improve application performance?

My ASP.NET Core application retrieves frequently requested data from SQL Server. I want to reduce database load and improve response times using Redis. How does Redis caching work, and what is the cache-aside pattern? Please explain cache expiration, cache invalidation, and how to prevent users from receiving outdated data.
