I have packed middleware,you can register it to startup or service.
such as :
//config it
services.AddAIpRateLimiting(Configuration);and then
app.UseMiddleware<RateLimitingMiddleware>(Array.Empty<object>());finally,to add appsettings.json parameters that adapt you application scenarios
"RateLimiting": {
"Times": 5000
},That's all.If you have any questions, please commit an issue.
