    ```kotlin
      private val client = OkHttpClient()

      fun run() {
        val request = Request.Builder()
            .url("https://publicobject.com/helloworld.txt")
            .build()

        client.newCall(request).execute().use { response ->
          if (!response.isSuccessful) throw IOException("Unexpected code $response")

            .sslSocketFactory(sslSocketFactory, trustManager)
            .build()
      }

      fun run() {
        val request = Request.Builder()
            .url("https://publicobject.com/helloworld.txt")
            .build()

        client.newCall(request).execute().use { response ->
          if (!response.isSuccessful) throw IOException("Unexpected code $response")

    printEvent("dnsEnd");

  ...
}
```

We make a couple calls:

```java
Request request = new Request.Builder()
    .url("https://publicobject.com/helloworld.txt")
    .build();

System.out.println("REQUEST 1 (new connection)");
try (Response response = client.newCall(request).execute()) {
  // Consume and discard the response body.
