En este ejemplo, las *path operations* bajo el `router` usarán la clase personalizada `TimedRoute`, y tendrán un header `X-Response-Time` extra en el response con el tiempo que tomó generar el response:

    }

    /**
     * Gets the response sequence number returned by the server.
     * This should match the request sequence number in a successful response.
     *
     * @return the response sequence number
     */
    public long getResponseSequenceNumber() {
        return responseSequenceNumber;
    }

    /**
     * Sets the response sequence number.

- **`org.codelibs.curl.CurlResponse`**: Response wrapper implementing `Closeable` for proper resource management
- **`org.codelibs.curl.CurlException`**: Unchecked exception for HTTP errors

### I/O Layer

- **`org.codelibs.curl.io.ContentCache`**: Handles automatic in-memory or on-disk caching of request/response bodies

Das ist nützlich für Vorgänge, die nach einem <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> ausgeführt werden müssen, bei denen der Client jedoch nicht unbedingt auf den Abschluss des Vorgangs warten muss, bevor er die Response erhält.

Hierzu zählen beispielsweise:

        .url("https://api.github.com/gists/c2a7c39532239ff261be")
        .build();
    try (Response response = client.newCall(request).execute()) {
      if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

      Gist gist = gistJsonAdapter.fromJson(response.body().source());

      for (Map.Entry<String, GistFile> entry : gist.files.entrySet()) {

    Request
      .Builder()
      .url(url)
      .build()
  try {
    client.newCall(request).execute().use { response ->
      val handshake = response.handshake
      println(
        "${handshake!!.tlsVersion} ${handshake.cipherSuite} ${response.protocol} " +
          "${response.code} ${response.body.bytes().size}b",
      )
    }
  } catch (ioe: IOException) {
    println(ioe)
  }
}

      // treats an incomplete response body as a ProtocolException.
    } catch (ioe: IOException) {
      // Change in https://bugs.openjdk.org/browse/JDK-8335135
      assertThat(ioe.message).isEqualTo("Premature EOF")
    }
  }

    val headers = response.build().headers
