限制 Azure 应用服务中的并发请求 [英] Limit concurrent requests in Azure App Service

问题描述

鉴于以下

• ASP.NET Web API 应用程序
• 目标:.NET Framework 4.6.1
• 作为 Azure 应用服务托管

我希望限制应用程序的并发 HTTP 请求总数.

I wish to restrict the total number of concurrent HTTP requests to the application.

我看过 https://github.com/stefanprodan/WebApiThrottle 但这似乎专注于不同的用例.

I have looked at https://github.com/stefanprodan/WebApiThrottle but that seems to be focused on different use cases.

我想要 IIS 中的此设置的等效项:https://forums.asp.net/t/1683143.aspx?Max+concurrent+requests

I would like the equivalent of this setting in IIS: https://forums.asp.net/t/1683143.aspx?Max+concurrent+requests

推荐答案

这是为了避免以适得其反的方式攻击后端服务.

This is to avoid attacking a backend service in counterproductive ways.

为避免攻击，您可以使用动态 IP 限制来限制并发请求.如果并发请求数大于设置值，IP地址将被阻塞.

To avoid the attack, you could restrict the concurrent requests using Dynamic IP Restrictions. If the concurrent requests count is larger than the setting value, the IP address will be blocked.

<system.webServer>
  <security>
    <dynamicIpSecurity>
      <denyByConcurrentRequests enabled="true" maxConcurrentRequests="30"/>
      <denyByRequestRate enabled="true" maxRequests="30" requestIntervalInMilliseconds="2000"/>
    </dynamicIpSecurity>
  </security>
</system.webServer>
