MinIO supports following FTP/SFTP based protocols to access and manage data.

- Secure File Transfer Protocol (SFTP) – Defined by the Internet Engineering Task Force (IETF) as an
  extended version of SSH 2.0, allowing file transfer over SSH and for use with Transport Layer
  Security (TLS) and VPN applications.

- File Transfer Protocol over SSL/TLS (FTPS) – Encrypted FTP communication via TLS certificates.

        throw UnknownServiceException("H2_PRIOR_KNOWLEDGE cannot be used with HTTPS")
      }
    }

   */
  fun requiresTunnel(): Boolean {
    if (proxy.type() != Proxy.Type.HTTP) return false
    return (address.sslSocketFactory != null) ||
      (Protocol.H2_PRIOR_KNOWLEDGE in address.protocols)

  }

Blocking APIs may be inefficient because you hold a thread idle while waiting on the network. Threads are expensive because they have both a memory overhead and a context-switching overhead.

#### Framed protocols

   *
   * For cipher suites, at least one of the [required cipher suites][cipherSuites] must match the
   * socket's enabled cipher suites. If there are no required cipher suites the socket must have at
   * least one cipher suite enabled.
   *
   * For protocols, at least one of the [required protocols][tlsVersions] must match the socket's
   * enabled protocols.

	}

	if len(match.ApplicationProtocols) > 0 {
		found := false
		for protDescr, protocols := range protDescrs {
			if reflect.DeepEqual(match.ApplicationProtocols, protocols) {
				found = true
				descrs = append(descrs, protDescr)
				break
			}
		}
		if !found {

    platform.assumeHttp2Support()
    setsNegotiatedProtocolHeader(Protocol.HTTP_2)
  }

  private fun setsNegotiatedProtocolHeader(protocol: Protocol) {
    enableProtocol(protocol)
    server.enqueue(
      MockResponse(body = "A"),
    )
    client =
      client.newBuilder()
        .protocols(Arrays.asList(protocol, Protocol.HTTP_1_1))
        .build()

## Configuration protocol

Ztunnel, of course, needs to be dynamically configured in order to make decisions on how it should handle traffic.
For this purpose, we chose to use xDS transport protocol due to our expertise and existing infrastructure, and because the protocol is well suited to our needs.

has been replaced with a new synthetic header, `OkHttp-Selected-Protocol`.

##### Changes

 * New: Support for `HTTP-draft-09/2.0`.
 * New: Support for `spdy/3.1`. Dropped support for `spdy/3`.
 * New: Use ALPN on Android platforms that support it (4.4+)
 * New: CacheControl model and parser.
 * New: Protocol selection in MockWebServer.
 * Fix: Route selection shouldn't use TLS modes that we know will fail.
