Si tienes dependencias con `yield`, el código de salida se ejecutará *después* del middleware.

Si hubiera alguna tarea en segundo plano (documentada más adelante), se ejecutará *después* de todo el middleware.

## Crear un middleware

Para crear un middleware usas el decorador `@app.middleware("http")` encima de una función.

La función middleware recibe:

* La `request`.
