.NET Core: Scaling with Redis and IDistributedCache

In-memory cache fails when you have multiple server instances. Use Distributed Caching to share data across your entire cluster.

// In Program.cs
builder.Services.AddStackExchangeRedisCache(options => {
    options.Configuration = "localhost:6379";
});

Now, when Server A caches a user’s session, Server B can access it immediately, ensuring a seamless user experience in a load-balanced environment.
