### Things to consider

MinIO redirects browser access requests to the configured server port (i.e. `127.0.0.1:9000`) to the configured Console port. MinIO uses the hostname or IP address specified in the request when building the redirect URL. The URL and port *must* be accessible by the client for the redirection to work.

次の章では、FastAPIアプリケーションをデプロイするための**具体的なレシピ**を紹介します。

しかし、今はこれらの重要な**コンセプトに基づくアイデア**を確認しましょう。これらのコンセプトは、他のどのタイプのWeb APIにも当てはまります。💡

## セキュリティ - HTTPS

<!-- NOTE: https.md written in Japanese does not exist, so it redirects to English one  -->
[前チャプターのHTTPSについて](https.md){.internal-link target=_blank}では、HTTPSがどのようにAPIを暗号化するのかについて学びました。

通常、アプリケーションサーバにとって**外部の**コンポーネントである**TLS Termination Proxy**によって提供されることが一般的です。このプロキシは通信の暗号化を担当します。

    // 2 direct + 2 redirect = 4
    assertThat(cache.requestCount()).isEqualTo(4)
    assertThat(cache.hitCount()).isEqualTo(2)
    assertThat(response2.handshake!!.cipherSuite).isEqualTo(
      response1.handshake!!.cipherSuite,
    )
  }

  /**
   * We've had bugs where caching and cross-protocol redirects yield class cast exceptions internal

  @Test
  fun response308WithPost() {
    testRedirect(false, "POST")
  }

  /**
   * In OkHttp 4.5 and earlier, HTTP 307 and 308 redirects were only honored if the request method
   * was GET or HEAD.
   *
   * In OkHttp 4.6 and later, HTTP 307 and 308 redirects are honored for all request methods.
   *
   * If you're upgrading to OkHttp 4.6 and would like to retain the previous behavior, install this

		// for i, c := range via {
		// 	fmt.Printf("Sofar %d: %s %s\n", i, c.Method, c.URL.String())
		// }
		// Save the last request in a redirect chain.
		lastReq = req
		// We do not follow redirect back to client application.
		if req.URL.Path == "/oauth_callback" {
			return http.ErrUseLastResponse
		}
		return nil
	}

	dexClient := http.Client{

  - Health check (liveness & readiness) probes using an HTTPGetAction will no longer follow redirects to different hostnames from the original probe request. Instead, these non-local redirects will be treated as a Success (the documented behavior). In this case an event with reason "ProbeWarning" will be generated, indicating that the redirect was ignored. If you were previously relying on the redirect to run health checks against different endpoints, you will need to perform the healthcheck logic...

 *  New: `EventListener.followUpDecision()` is called each time a response is received. It notifies
    your listener if OkHttp has decided to make a follow-up request. Some common follow-ups are
    authentication challenges and redirects.

 *  New: Handy constants for `Headers.EMPTY`, `RequestBody.EMPTY`, and `ResponseBody.EMPTY`.

 *  New: OkHttp now calls `StrictMode.noteSlowCall()` when initializing TLS on Android. Use

	// PathEndpointType - path style endpoint type enum.
	PathEndpointType EndpointType = iota + 1

	// URLEndpointType - URL style endpoint type enum.
	URLEndpointType
)

// ProxyEndpoint - endpoint used for proxy redirects
// See proxyRequest() for details.
type ProxyEndpoint struct {
	Endpoint
	Transport http.RoundTripper
}

// Node holds information about a node in this cluster
type Node struct {
	*url.URL
	Pools    []int

    take and covers resolving DNS, connecting, writing the request body, server processing, and
    reading the full response body. If a call requires redirects or retries all must complete within
    one timeout period.

    Use `OkHttpClient.Builder.callTimeout()` to specify the default duration and `Call.timeout()` to
    specify the timeout of an individual call.
