# Including WSGI - Flask, Django, others { #including-wsgi-flask-django-others }

You can mount WSGI applications as you saw with [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank}, [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank}.

For that, you can use the `WSGIMiddleware` and use it to wrap your WSGI application, for example, Flask, Django, etc.

## Using `WSGIMiddleware` { #using-wsgimiddleware }

Deshalb, um ID-Kollisionen zu vermeiden, könnten Sie beim Erstellen des JWT-Tokens für den Benutzer, dem Wert des `sub`-Schlüssels ein Präfix, z. B. `username:` voranstellen. In diesem Beispiel hätte der Wert von `sub` also auch `username:johndoe` sein können.

Der wesentliche Punkt ist, dass der `sub`-Schlüssel in der gesamten Anwendung eine eindeutige Kennung haben sollte, und er sollte ein String sein.

## Es testen

Entonces, para evitar colisiones de ID, cuando crees el token JWT para el usuario, podrías prefijar el valor de la clave `sub`, por ejemplo, con `username:`. Así, en este ejemplo, el valor de `sub` podría haber sido: `username:johndoe`.

Lo importante a tener en cuenta es que la clave `sub` debería tener un identificador único a lo largo de toda la aplicación, y debería ser un string.
