ASP.NET Core Rate Limiter Middleware

A guide explaining how ASP.NET Core's Rate Limiter Middleware can be used to protect ServiceStack APIs and Apps from abuse


This episode looks at how to use ASP.NET Core's built-in rate limiting middleware to protect web APIs and applications from excessive traffic.

It outlines the basic configuration for setting up rate limiting based on client IP address or client ID and then explores more advanced options for customizing the behavior, such as implementing a sliding window algorithm to allow short bursts of requests while constraining the average rate.

The text then delves into per-user rate limiting for multi-tenant SaaS applications, explaining how to leverage ASP.NET Core Identity to authenticate users and retrieve their plan details, and then configure the rate limiter accordingly.

By combining ASP.NET Core rate limiting with ASP.NET Core Identity, developers can create flexible and effective per-user rate limits that ensure fair usage and protect applications from abuse.
