## Test using MinIO Client `mc`

    val request1 = Request.Builder().url(server.url("/")).build()
    val response1 = client.newCall(request1).execute()
    val certificatePinnerBuilder = CertificatePinner.Builder()
    for (certificate in response1.handshake!!.peerCertificates) {
      certificatePinnerBuilder.add(
        server.hostName,
        pin(certificate),
      )
    }

```
mc cp myphoto.jpg myminio/images
```

In the previous terminal, you will now see the operation that MinIO performs on Redis:

```

    client = client.newBuilder().certificatePinner(certificatePinner).build()

    server.enqueue(MockResponse(body = "abc"))
