Owin middleware that implements the leaky bucket algorithm for request throttling.

Build status Coverage Status NuGet

This package is available via install the NuGet:

Install-Package LeakyBucket.Owin

Then, you can enable LeakyBucket rate limiting by adding the LeakyBucketMiddleware to the Owin app:

using System;
using LeakyBucket.Owin;
using Microsoft.Owin;
using Owin;

[assembly: OwinStartup(typeof(MyWebApp.Startup))]

namespace MyWebApp
    public partial class Startup
        public void Configuration(IAppBuilder app)
            app.UseLeakyBucket(new LeakyBucketConfiguration
              MaxNumberOfRequests = 100,
              RefreshRate = TimeSpan.FromSeconds(1)

How it works

  1. When a request comes in it will extract the IClientIdentifier from the IOwinContext with the function specified in the configuration.
  2. It will check for any requests that have passed the specified RefreshRate and remove them from the IRequestStore.
  3. It will then add the new request to the IRequestStore.
  4. It will check how many requests are remaining.
  5. If it exceeds the MaxNumberOfRequests then it will return a 429 Too Many Requests status code, otherwise it will continue on with the request.


The LeakyBucketConfiguration can specifiy an IRequestStore, that is set to the DefaultRequestStore by default, which is responsible for holding the current number of requests for each client.

The LeakyBucketConfiguration can specifies a function that determines what a client is. By default it creates a DefaultClientIdentifier that holds a reference to the remote address.
