In OkHttp some fields of the address come from the URL (scheme, hostname, port) and the rest come from the [OkHttpClient](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/).

    val multipartBody: MultipartBody = builder.build()
  }

  @Test
  fun okHttpClient() {
    val client: OkHttpClient = OkHttpClient()
    val dispatcher: Dispatcher = client.dispatcher
    val proxy: Proxy? = client.proxy
    val protocols: List<Protocol> = client.protocols

    this because it only occurs if you have proxy configured and you share a connection pool among
    multiple `OkHttpClient` instances.

    This particularly-subtle bug was caused by us assigning each `OkHttpClient` instance its own
    `NullProxySelector` when an explicit proxy is configured. But we don't share connections when
    the proxy selectors are different. Ugh!

    OkHttp 2 the built-in disk cache is the only supported response cache.

 *  **HttpResponseCache has been renamed to Cache.** Install it with
    `OkHttpClient.setCache(...)` instead of `OkHttpClient.setResponseCache(...)`.

 *  **OkAuthenticator has been replaced with Authenticator.** This new
    authenticator has access to the full incoming response and can respond with
