fun proxyMoveTest(cleanClose: Boolean) {
    // Define a single Proxy at myproxy:8008 that will artificially move during the test
    val proxySelector = RecordingProxySelector()
    val socketAddress = InetSocketAddress.createUnresolved("myproxy", 8008)
    proxySelector.proxies.add(Proxy(Proxy.Type.HTTP, socketAddress))

    // Define two host names for the DNS routing of fake proxy servers

In many situations, you would use a **proxy** like Traefik or Nginx in front of your FastAPI app.

These proxies could handle HTTPS certificates and other things.

## Proxy Forwarded Headers { #proxy-forwarded-headers }

    * Otherwise, you might have to stop the TLS Termination Proxy momentarily, start the renewal program to acquire the certificates, then configure them with the TLS Termination Proxy, and then restart the TLS Termination Proxy. This is not ideal, as your app(s) will not be available during the time that the TLS Termination Proxy is off.

    * Esta es una de las razones por las que es muy útil cuando el mismo TLS Termination Proxy también se encarga del proceso de renovación del certificado.

    val method = userResponse.request.method
    when (responseCode) {
      HTTP_PROXY_AUTH -> {
        val selectedProxy = route!!.proxy
        if (selectedProxy.type() != Proxy.Type.HTTP) {
          throw ProtocolException("Received HTTP_PROXY_AUTH (407) code while not using proxy")
        }
        return client.proxyAuthenticator.authenticate(route, userResponse)
      }

    * Caso contrário, você pode ter que parar a execução do Proxy de Terminação TLS momentaneamente, inicializar o programa de renovação para renovar os certificados, e então reiniciar o Proxy de Terminação TLS. Isso não é o ideal, já que sua(s) aplicação(ões) não vão estar disponíveis enquanto o Proxy de Terminação TLS estiver desligado.

    * これは、同じTLS Termination Proxyが証明書の更新処理も行う場合に非常に便利な理由の1つです。
    * そうでなければ、TLS Termination Proxyを一時的に停止し、証明書を取得するために更新プログラムを起動し、TLS Termination Proxyで証明書を設定し、TLS Termination Proxyを再起動しなければならないかもしれません。TLS Termination Proxyが停止している間はアプリが利用できなくなるため、これは理想的ではありません。


アプリを提供しながらこのような更新処理を行うことは、アプリケーション・サーバー（Uvicornなど）でTLS証明書を直接使用するのではなく、TLS Termination Proxyを使用して**HTTPSを処理する別のシステム**を用意したくなる主な理由の1つです。

## まとめ

Prometheus sets the `Host` header to `domain:port` as part of HTTP operations against the MinIO metrics endpoint. For MinIO deployments behind a load balancer, reverse proxy, or other control plane (HAProxy, nginx, pfsense, opnsense, etc.), ensure the network service supports routing these requests to the deployment.

        factory.newAddress(uriHost = "example.com", uriPort = 1003),

                    }

                    Proxy p = new Proxy();
                    p.setHost(proxy.getHost());
                    p.setProtocol(proxy.getProtocol());

                    p.setNonProxyHosts(proxy.getNonProxyHosts());
                    p.setUserName(proxy.getUsername());
                    p.setPassword(proxy.getPassword());
