You can implement rate limiting in a .NET Web API by configuring policies with specific permit limits, window durations, and queue sizes. This protects endpoints like login routes by restricting requests from a single IP address to prevent abuse.

IP-based partitioning for rate limiting policies categorizes incoming traffic by client IP address. This mechanism ensures that permit limits and window durations are tracked individually per IP, isolating abusive clients without affecting other users.

To apply a rate limit policy to specific API endpoints, you use endpoint attributes. This applies the configured permit limits, window durations, and queue sizes directly to the targeted routes to control access and manage traffic.

Yes, you can configure a queue for excess requests when rate limiting .NET Web API endpoints. Policies support defining specific queue sizes to hold incoming requests temporarily within the window duration before returning a 429 Too Many Requests response.

Yes, applying rate limiting policies in .NET automatically adds a 429 Too Many Requests response. When a client exceeds the configured permit limit within the window duration, the API rejects the request and returns this specific status code.

The best way to limit API requests to 10 per minute in .NET is to define a custom policy with a permit limit of 10 and a window duration of one minute. You can then apply this policy via attributes to your Web API endpoints.
