# Behind a Proxy { #behind-a-proxy }

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.

#### Detrás de un Proxy de Terminación TLS

Si estás ejecutando tu contenedor detrás de un Proxy de Terminación TLS (load balancer) como Nginx o Traefik, añade la opción `--proxy-headers`, esto le dirá a Uvicorn (a través de la CLI de FastAPI) que confíe en los headers enviados por ese proxy indicando que la aplicación se está ejecutando detrás de HTTPS, etc.

```Dockerfile

                    }

                    Proxy p = new Proxy();
                    p.setHost(proxy.getHost());
                    p.setProtocol(proxy.getProtocol());
                    p.setPort(proxy.getPort());
                    p.setNonProxyHosts(proxy.getNonProxyHosts());
                    p.setUserName(proxy.getUsername());
                    p.setPassword(proxy.getPassword());

      certificatePinner = null,
      proxyAuthenticator = proxyAuthenticator,
      proxy = proxy,
      protocols = protocols,
      connectionSpecs = connectionSpecs,
      proxySelector = proxySelector,
    )

  fun newRoute(
    address: Address = newAddress(),
    proxy: Proxy = this.proxy,
    socketAddress: InetSocketAddress = InetSocketAddress.createUnresolved(uriHost, uriPort),
  ): Route =

                            proxy = result.getProxy();

                            ProxyInfo proxyInfo = new ProxyInfo();
                            proxyInfo.setHost(proxy.getHost());
                            proxyInfo.setType(proxy.getProtocol());
                            proxyInfo.setPort(proxy.getPort());
                            proxyInfo.setNonProxyHosts(proxy.getNonProxyHosts());

    * 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.

    * 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.
