Implementing Rate Limiting in .NET with Redis Easily
In this post, we explore how to implement rate limiting and throttling in .NET APIs using Redis. We’ll look at native support in .NET 7+, and then go beyond with Redis to build distributed, production-ready solutions. You’ll see how to implement fixed window, sliding window with sorted sets, and token bucket using Lua — all fully integrated into your ASP.NET Core app with minimal effort. By the end, you’ll have everything you need to protect your APIs, handle bursts, and keep your backend stable and fair.
