The HttpURLConnection API is a blocking API. You make a blocking write to send a request, and a blocking read to receive the response.

#### Blocking APIs

Blocking APIs are convenient because you get top-to-bottom procedural code without indirection. Network calls work like regular method calls: ask for data and it is returned. If the request fails, you get a stacktrace right where the call was made.

        .addHeader("h1", "v1")
        .addHeader("h2", "v2")
        .trailers(headersOf("trailers", "boom"))
        .streamHandler(body)
        .build(),
    )
    val call =
      client.newCall(
        Request.Builder()
          .url(server.url("/"))
