しかし、**アプリケーションサーバー**が**プロキシ**から送信される*forwarded*ヘッダーを信頼するように設定できます。FastAPI CLIを使用している場合は、*CLI Option* `--forwarded-allow-ips` を使って、どのIPからの*forwarded*ヘッダーを信頼すべきかを指定できます。

たとえば、**アプリケーションサーバー**が信頼できる**プロキシ**からの通信のみを受け取っている場合、`--forwarded-allow-ips="*"` に設定して、受信するすべてのIPを信頼するようにできます。受け取るリクエストは、**プロキシ**が使用するIPからのものだけになるためです。

こうすることで、アプリケーションは、HTTPSを使用しているかどうか、ドメインなど、自身のパブリックURLが何であるかを把握できるようになります。

### [Flask](https://flask.palletsprojects.com) { #flask }

Flask is a "microframework", it doesn't include database integrations nor many of the things that come by default in Django.

This simplicity and flexibility allow doing things like using NoSQL databases as the main data storage system.

As it is very simple, it's relatively intuitive to learn, although the documentation gets somewhat technical at some points.
