   * The deadline to respond to this ping attempts to limit the cost of being wrong. If it is too
   * long, streams created while we await the pong will reuse broken connections and inevitably
   * fail. If it is too short, slow connections will be marked as failed and extra TCP and TLS
   * handshakes will be required.

 * forgiving: it will automatically percent-encode the `|'` yielding `http://example.com/abc%7Cdef`.
 * This kind behavior is consistent with web browsers. `HttpUrl` prefers consistency with major web
 * browsers over consistency with obsolete specifications.

 * ### Paths and Queries should decompose

 * Neither of the built-in URL models offer direct access to path segments or query parameters.

FastAPI アプリケーションでは、Uvicorn を実行する `fastapi` コマンドのようなサーバープログラムを使用し、**1つのプロセス**で1度に複数のクライアントに同時に対応できます。

しかし、多くの場合、複数のワーカー・プロセスを同時に実行したいと考えるでしょう。

### 複数のプロセス - Worker { #multiple-processes-workers }

クライアントの数が単一のプロセスで処理できる数を超えており（たとえば仮想マシンがそれほど大きくない場合）、かつサーバーの CPU に**複数のコア**がある場合、同じアプリケーションで同時に**複数のプロセス**を実行させ、すべてのリクエストを分散させることができます。

同じAPIプログラムの**複数のプロセス**を実行する場合、それらは一般的に**Worker／ワーカー**と呼ばれます。
