### Antes y después de la `response`

Puedes añadir código que se ejecute con la `request`, antes de que cualquier *path operation* la reciba.

Y también después de que se genere la `response`, antes de devolverla.

Por ejemplo, podrías añadir un custom header `X-Process-Time` que contenga el tiempo en segundos que tomó procesar la request y generar una response:

/**
 * Utility class for handling response data.
 */
public final class ResponseDataUtil {

    /**
     * Private constructor to prevent instantiation of this utility class.
     */
    private ResponseDataUtil() {
    }

    /**
     * Creates a temporary file containing the response body from the given ResponseData.
     *
     * @param responseData the response data containing the response body

          e: IOException,
        ) {
          println("failed: $e")
        }

        override fun onResponse(
          call: Call,
          response: Response,
        ) {
          println("response: ${response.code}")
          response.close()
        }
      },
    )
  }

        .url("https://en.wikipedia.org/w/index.php")
        .post(formBody)
        .build();

    try (Response response = client.newCall(request).execute()) {
      if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

      System.out.println(response.body().string());
    }
  }

  public static void main(String... args) throws Exception {
    new PostForm().run();
  }

     * The content cache that stores the response content.
     */
    private ContentCache contentCache;

    /**
     * The encoding used for the response content.
     */
    private String encoding;

    /**
     * The exception that occurred while accessing the content, if any.
     */
    private Exception contentException;

    /**
     * The headers of the response.
     */
