own mounted sub-applications and everything would work correctly, because FastAPI handles all these `root_path`s automatically.

You will learn more about the `root_path` and how to use it explicitly in the section about [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank}....

  /**
   * Intercepts calls to a {@code Map} to check that {@code setUpRan} is true when they happen. Then

    this because it only occurs if you have proxy configured and you share a connection pool among
    multiple `OkHttpClient` instances.

    This particularly-subtle bug was caused by us assigning each `OkHttpClient` instance its own
    `NullProxySelector` when an explicit proxy is configured. But we don't share connections when
    the proxy selectors are different. Ugh!

Вы можете монтировать WSGI‑приложения, как вы видели в [Подприложения — Mounts](sub-applications.md){.internal-link target=_blank}, [За прокси‑сервером](behind-a-proxy.md){.internal-link target=_blank}.

Для этого вы можете использовать `WSGIMiddleware` и обернуть им ваше WSGI‑приложение, например Flask, Django и т.д.
