/// tip | Tipp

Der eigentliche Callback ist nur ein HTTP-Request.

Wenn Sie den Callback selbst implementieren, können Sie beispielsweise [HTTPX](https://www.python-httpx.org) oder [Requests](https://requests.readthedocs.io/) verwenden.

///

## Schreiben des Codes, der den Callback dokumentiert { #write-the-callback-documentation-code }

It uses a single two-way connection to send and receive messages between servers.

It includes built in muxing of concurrent requests as well as congestion handling for streams.

Requests can be "Single Payload" or "Streamed".

Use the MinIO Grid for:

* Small, frequent requests with low latency requirements.
* Long-running requests with small/medium payloads.

Do *not* use the MinIO Grid for:

* Large payloads.

## Requests ohne Content-Type erlauben { #allowing-requests-without-content-type }

Wenn Sie Clients unterstützen müssen, die keinen `Content-Type`-Header senden, können Sie die strikte Prüfung deaktivieren, indem Sie `strict_content_type=False` setzen:

### CORS preflight requests { #cors-preflight-requests }

These are any `OPTIONS` request with `Origin` and `Access-Control-Request-Method` headers.

In this case the middleware will intercept the incoming request and respond with appropriate CORS headers, and either a `200` or `400` response for informational purposes.

### Simple requests { #simple-requests }

## Allowing Requests Without Content-Type { #allowing-requests-without-content-type }

If you need to support clients that don't send a `Content-Type` header, you can disable strict checking by setting `strict_content_type=False`:

{* ../../docs_src/strict_content_type/tutorial001_py310.py hl[4] *}

## `HTTPSRedirectMiddleware` { #httpsredirectmiddleware }

Impone que todas las requests entrantes deben ser `https` o `wss`.

Cualquier request entrante a `http` o `ws` será redirigida al esquema seguro.
