/// note | Teknik Detaylar

`from starlette import status` da kullanabilirsiniz.

**FastAPI**, geliştirici olarak size kolaylık olsun diye `starlette.status`'u `fastapi.status` olarak da sunar. Ancak bu aslında doğrudan Starlette'den gelir.

///

## Varsayılanı değiştirmek { #changing-the-default }

/// note | Détails techniques

Vous pourriez aussi utiliser `from starlette.responses import HTMLResponse`.

**FastAPI** fournit les mêmes `starlette.responses` sous `fastapi.responses` simplement pour votre confort de développement. Mais la plupart des réponses disponibles viennent directement de Starlette.

///

### `Response` { #response }

==== Distribution

By default a node is started with the zip distribution.
In order to start with a different distribution use the `-Drun.distribution` argument.

To for example start the open source distribution:

-------------------------------------
./gradlew run -Drun.distribution=oss
-------------------------------------

==== License type

By default a node is started with the `basic` license type.

І саме ці дві сутності - `scope` та `receive` - потрібні для створення нового екземпляра `Request`.

Щоб дізнатися більше про `Request`, перегляньте [документацію Starlette про запити](https://www.starlette.dev/requests/).

///

Єдине, що робить інакше функція, повернена `GzipRequest.get_route_handler`, - перетворює `Request` на `GzipRequest`.
