Register an _application_ interceptor by calling `addInterceptor()` on `OkHttpClient.Builder`:

```java
OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(new LoggingInterceptor())
    .build();

Request request = new Request.Builder()
    .url("http://www.publicobject.com/helloworld.txt")
    .header("User-Agent", "OkHttp Example")
    .build();

      Throwable cause, Class<X> exceptionClass) throws X {
    if (cause instanceof Error) {
      throw new ExecutionError((Error) cause);
    }
    if (cause instanceof RuntimeException) {
      throw new UncheckedExecutionException(cause);
    }
    throw newWithCause(exceptionClass, cause);
  }
