## Teknik Detaylar { #technical-details }

FastAPI, bazı SSE en iyi uygulamalarını kutudan çıktığı gibi uygular.

- [HTML spesifikasyonu: Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html#authoring-notes) önerisine uygun olarak, bazı proxy'lerin bağlantıyı kapatmasını önlemek için, 15 saniye boyunca hiç mesaj gelmezse **"keep alive" `ping` yorumu** gönderir.

- Устанавливать заголовок `Cache-Control: no-cache`, чтобы предотвратить кэширование потока.

## Incluir el mismo router múltiples veces con diferentes `prefix` { #include-the-same-router-multiple-times-with-different-prefix }

También puedes usar `.include_router()` múltiples veces con el *mismo* router usando diferentes prefijos.

 * read operations will work correctly if the last write <i>happens-before</i> any reads. To allow
 * concurrent update operations, wrap your multimap with a call to {@link
 * Multimaps#synchronizedSetMultimap}.
 *
 * <p><b>Warning:</b> Do not modify either a key <i>or a value</i> of a {@code HashMultimap} in a
 * way that affects its {@link Object#equals} behavior. Undefined behavior and bugs will result.

Lo mismo sucedería si tuvieras algo como una <dfn title='una unión entre múltiples tipos significa "cualquiera de estos tipos".'>unión</dfn> entre diferentes tipos donde uno o más de ellos no son tipos válidos de Pydantic, por ejemplo esto fallaría 💥:

///

## Sin Pydantic { #without-pydantic }

	ExecObjectLayerAPITest(ExecObjectLayerAPITestArgs{t: t, objAPITest: testListMultipartUploadsHandler, endpoints: []string{"ListMultipartUploads"}})
}

// testListMultipartUploadsHandler - Tests validate listing of multipart uploads.
func testListMultipartUploadsHandler(obj ObjectLayer, instanceType, bucketName string, apiRouter http.Handler,
	credentials auth.Credentials, t *testing.T,
) {

 *
 * <p>This class is not threadsafe when any concurrent operations update the multimap. Concurrent
 * read operations will work correctly. To allow concurrent update operations, wrap your multimap
 * with a call to {@link Multimaps#synchronizedListMultimap}.
