En el camino de la request, el middleware más externo se ejecuta primero.

En el camino de la response, se ejecuta al final.

Por ejemplo:

```Python
app.add_middleware(MiddlewareA)
app.add_middleware(MiddlewareB)
```

Esto da como resultado el siguiente orden de ejecución:

* **Request**: MiddlewareB → MiddlewareA → ruta
