---------------------

The above scenario is representative of most TLS set ups: the client uses certificates to validate
the identity of a server. The converse is also possible. Here we create a server that authenticates
a client and a client that authenticates a server.

```java
// Create the root for client and server to trust. We could also use different roots for each!
HeldCertificate rootCertificate = new HeldCertificate.Builder()

  private lateinit var server: MockWebServer
  private val handshakeCertificates = platform.localhostHandshakeCertificates()
  private var client: OkHttpClient = clientTestRule.newClient()

  @BeforeEach
  fun setUp(server: MockWebServer) {
    this.server = server
  }

  @Test
  fun connectionsAreReused() {
    server.enqueue(MockResponse(body = "a"))
    server.enqueue(MockResponse(body = "b"))

Such a special COPY request is also known as S3 SSE-C key rotation.

### Server-Side Encryption with a KMS

SSE-S3 allows an S3 client to en/decrypt an object at the MinIO server using a KMS. The MinIO
server only assumes that the KMS provides two services:

    upstream minio {
        server minio1:9000 max_fails=1 fail_timeout=10s;
        server minio2:9000 max_fails=1 fail_timeout=10s;
        server minio3:9000 max_fails=1 fail_timeout=10s;
        server minio4:9000 max_fails=1 fail_timeout=10s;
    }

    upstream console {
        ip_hash;
        server minio1:9001;
        server minio2:9001;
        server minio3:9001;
        server minio4:9001;
    }

  @Test
  fun multipleDnsLookupsForSingleCall() {
    server.enqueue(
      MockResponse.Builder()
        .code(301)
        .setHeader("Location", "http://www.fakeurl:" + server.port)
        .build(),
    )
    server.enqueue(MockResponse())
    val dns = FakeDns()
    dns["fakeurl"] = client.dns.lookup(server.hostName)
    dns["www.fakeurl"] = client.dns.lookup(server.hostName)
    client =
      client.newBuilder()

			t.Fatalf("Case %v: server.Addrs: expected: %v, got: %v", (i + 1), testCase.addrs, server.Addrs)
		}

		if testCase.certFn == nil {
			if server.TLSConfig != nil {
				t.Fatalf("Case %v: server.TLSConfig: expected: <nil>, got: %v", (i + 1), server.TLSConfig)
			}
		} else {
			if server.TLSConfig == nil {
				t.Fatalf("Case %v: server.TLSConfig: expected: <non-nil>, got: <nil>", (i + 1))
			}
		}

To host multiple tenants on a single machine, run one MinIO Server per tenant with a dedicated HTTPS port, configuration, and data directory.

### 1.1 Host Multiple Tenants on a Single Drive

Use the following commands to host 3 tenants on a single drive:

```sh
minio server --address :9001 /data/tenant1
minio server --address :9002 /data/tenant2
minio server --address :9003 /data/tenant3
```

    assertThat(webSocket.receivedPongCount()).isEqualTo(0)
    assertThat(server.sentPingCount()).isEqualTo(0)
    assertThat(server.receivedPingCount()).isEqualTo(0)
    assertThat(server.receivedPongCount()).isEqualTo(0)
    closeWebSockets(webSocket, server)
  }
