// First call should read the file
        NbtAddress result1 = lmhosts.getByName("TESTHOST", mockContext);
        assertNotNull(result1);

        // Second call should use cached data (file not modified)
        NbtAddress result2 = lmhosts.getByName("TESTHOST", mockContext);

    @Test

* `filename` - Si se establece, se incluirá en el response `Content-Disposition`.

Los responses de archivos incluirán los headers apropiados `Content-Length`, `Last-Modified` y `ETag`.

{* ../../docs_src/custom_response/tutorial009_py39.py hl[2,10] *}

También puedes usar el parámetro `response_class`:

{* ../../docs_src/custom_response/tutorial009b_py39.py hl[2,8,10] *}

#### `lru_cache` Technical Details { #lru-cache-technical-details }

`@lru_cache` modifies the function it decorates to return the same value that was returned the first time, instead of computing it again, executing the code of the function every time.

    /** The key of the message: by Last Modified (asc) */
    public static final String LABELS_search_result_sort_last_modified_asc = "{labels.search_result_sort_last_modified_asc}";

    /** The key of the message: by Last Modified (desc) */
    public static final String LABELS_search_result_sort_last_modified_desc = "{labels.search_result_sort_last_modified_desc}";

Mas, infelizmente, você não obtém nada útil:

### Adicionar tipos { #add-types }

Vamos modificar uma única linha da versão anterior.

Vamos mudar exatamente esse fragmento, os parâmetros da função, de:

```Python
    first_name, last_name
```

para:

```Python
    first_name: str, last_name: str

* `filename` - If set, this will be included in the response `Content-Disposition`.

File responses will include appropriate `Content-Length`, `Last-Modified` and `ETag` headers.

{* ../../docs_src/custom_response/tutorial009_py39.py hl[2,10] *}

You can also use the `response_class` parameter:

{* ../../docs_src/custom_response/tutorial009b_py39.py hl[2,8,10] *}

* `filename` – Wenn gesetzt, wird das in der `Content-Disposition` der Response eingefügt.

Datei-Responses enthalten die entsprechenden `Content-Length`-, `Last-Modified`- und `ETag`-Header.

{* ../../docs_src/custom_response/tutorial009_py39.py hl[2,10] *}

Sie können auch den Parameter `response_class` verwenden:

        : Lists.newArrayList(iterable.iterator());
  }

  /**
   * Adds all elements in {@code iterable} to {@code collection}.
   *
   * @return {@code true} if {@code collection} was modified as a result of this operation.
   */
  @CanIgnoreReturnValue
  public static <T extends @Nullable Object> boolean addAll(
      Collection<T> addTo, Iterable<? extends T> elementsToAdd) {

  /**
   * Returns a <b>mutable</b> list containing {@code elements} sorted by this ordering; use this
   * only when the resulting list may need further modification, or may contain {@code null}. The
   * input is not modified. The returned list is serializable and has random access.
   *
   * <p>Unlike {@link Sets#newTreeSet(Iterable)}, this method does not discard elements that are

Para hacer eso, y para acomodar diferentes necesidades de aplicaciones, hay varias formas en que puede hacerlo. Algunas formas populares son:

* **Modificar algunos registros DNS**.
    * Para esto, el programa de renovación necesita soportar las API del proveedor de DNS, por lo que, dependiendo del proveedor de DNS que estés utilizando, esto podría o no ser una opción.
