That tells the browser to show the integrated prompt for a username and password.

Then, when you type that username and password, the browser sends them in the header automatically.

that custom proprietary headers can be added <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">using the 'X-' prefix</a>.

But if you have custom headers that you want a client in a browser to be able to see, you need to add them to your CORS configurations (read more in [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md){.internal-link target=_blank}), using the parameter `expose_headers` documented in <a href="https://www....

Distributed instances are now accessible on the host using the Minio CLI on port 9000 and the Minio Web Console on port 9001. Proceed to access the Web browser at <http://127.0.0.1:9001/>. Here 4 MinIO server instances are reverse proxied through Nginx load balancing.

### Notes

```Python hl_lines="6-7"
{!../../../docs_src/query_params/tutorial005.py!}
```

Hier ist `needy` ein erforderlicher Query-Parameter vom Typ `str`.

Wenn Sie in Ihrem Browser eine URL wie:

```
http://127.0.0.1:8000/items/foo-item
```

... öffnen, ohne den benötigten Parameter `needy`, dann erhalten Sie einen Fehler wie den folgenden:

```JSON

## 3. Test your setup

To test this setup, access the MinIO server via browser or [`mc`](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart).

But before that, handling asynchronous code was quite more complex and difficult.

In previous versions of Python, you could have used threads or <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>. But the code is way more complex to understand, debug, and think about.
