Most of these ideas would be more or less **independent**, and in most cases you should only need to study them if they apply directly to **your project**.

If something seems interesting and useful to your project, go ahead and check it, but otherwise, you might probably just skip them.

/// tip

Wrappen Sie dann die WSGI-Anwendung (z. B. Flask) mit der Middleware.

Und dann mounten Sie das auf einem Pfad.

{* ../../docs_src/wsgi/tutorial001_py39.py hl[2:3,3] *}

## Es testen { #check-it }

Jetzt wird jeder <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> unter dem Pfad `/v1/` von der Flask-Anwendung verarbeitet.

Und der Rest wird von **FastAPI** gehandhabt.

As we cannot just isolate them and "mount" them independently of the rest, the *path operations* are "cloned" (re-created), not included directly.
