## `TrustedHostMiddleware` { #trustedhostmiddleware }

Impone que todas las requests entrantes tengan correctamente configurado el header `Host`, para proteger contra ataques de HTTP Host Header.

Se soportan los siguientes argumentos:

You probably won't need to use it directly in your code.

But in case you needed it for an advanced scenario, you can add custom headers:

{* ../../docs_src/handling_errors/tutorial002_py39.py hl[14] *}

## Install custom exception handlers { #install-custom-exception-handlers }

You can declare a parameter of type `Response` in your *path operation function*.

And then you can set cookies in that *temporal* response object.

{* ../../docs_src/response_cookies/tutorial002_py39.py hl[1, 8:9] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

Вы можете объявить параметр типа `Response` в вашей функции-обработчике пути (как можно сделать и для cookie).

А затем вы можете устанавливать HTTP-заголовки в этом *временном* объекте ответа.

{* ../../docs_src/response_headers/tutorial002_py39.py hl[1, 7:8] *}

После этого вы можете вернуть любой нужный объект, как обычно (например, `dict`, модель из базы данных и т.д.).
