#### Conclusion

Dans ce scénario des "burgers du fast-food avec votre crush", comme il y a beaucoup d'attente 🕙, il est très logique d'avoir un système concurrent ⏸🔀⏯.

Et c'est le cas pour la plupart des applications web.

Vous aurez de nombreux, nombreux utilisateurs, mais votre serveur attendra 🕙 que leur connexion peu performante envoie des requêtes.

Puis vous attendrez 🕙 de nouveau que leurs réponses reviennent.

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Application startup complete.
```

</div>

In the output, there's a line with something like:

```hl_lines="4"

如果不想让 **FastAPI** 包含使用 `root_path` 的自动服务器，则要使用参数 `root_path_in_servers=False`：

{* ../../docs_src/behind_a_proxy/tutorial004.py hl[9] *}

这样，就不会在 OpenAPI 概图中包含服务器了。

## 挂载子应用

如需挂载子应用（详见 [子应用 - 挂载](sub-applications.md){.internal-link target=_blank}），也要通过 `root_path` 使用代理，这与正常应用一样，别无二致。

## 서브 애플리케이션

OAuth2 with scopes is the mechanism used by many big authentication providers, like Facebook, Google, GitHub, Microsoft, X (Twitter), etc. They use it to provide specific permissions to users and applications.

Every time you "log in with" Facebook, Google, GitHub, Microsoft, X (Twitter), that application is using OAuth2 with scopes.

cache responses, you'll need a cache directory that you can read and write to, and a limit on the cache's size. The cache directory should be private, and untrusted applications should not be able to read its contents!

It is an error to have multiple caches accessing the same cache directory simultaneously. Most applications should call `new OkHttpClient()` exactly once, configure it with their cache, and use that same instance everywhere. Otherwise the two cache instances will stomp on...

e então ele não será incluído no OpenAPI schema.

## Montando uma sub-aplicação { #mounting-a-sub-application }

Se você precisar montar uma sub-aplicação (como descrito em [Sub-aplicações - Montagens](sub-applications.md){.internal-link target=_blank}) enquanto também usa um proxy com `root_path`, você pode fazer isso normalmente, como esperaria.

For active-active replication, automatic failover occurs on `GET/HEAD` operations if object or object version requested qualifies for replication and is missing on one site, but present on the other. This allows the applications to take full advantage of two-way replication even before the two sites get fully synced.

Клиент (браузер) узнает, что ответ пришёл от правильного сервера, потому что используется способ шифрования, о котором они договорились ранее с помощью **HTTPS‑сертификата**.

### Несколько приложений { #multiple-applications }

На одном и том же сервере (или серверах) могут работать **несколько приложений**, например другие программы с API или база данных.
