# 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.

# Adicionando WSGI - Flask, Django, entre outros

Como você viu em [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank} e [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank}, você pode **"montar"** aplicações WSGI.

Para isso, você pode utilizar o `WSGIMiddleware` para encapsular a sua aplicação WSGI, como por exemplo Flask, Django, etc.

## Usando o `WSGIMiddleware`

Você precisa importar o `WSGIMiddleware`.
