How does .NET Core support advanced API throttling and quota management?
Updated Apr 28, 2026
Short answer
.NET Core supports advanced API throttling and quota management using built-in rate limiting middleware, token bucket and fixed window algorithms, custom middleware, distributed rate limiting (Redis-based), and integration with API gateways for global enforcement.

Deep explanation
API throttling and quota management ensure that clients do not overload a system by limiting:
- Requests per second (rate limiting)
- Requests per time window (quota)
- Concurrent requests
- Per-user, per-IP, or per-API-key usage
In ASP.NET Core, these controls can be implemented at multiple layers:
- Application layer (middleware)
- Gateway layer
- Distributed cache layer
- Cloud infrastructure layer
