* 次に、アプリケーションの残りの部分に**リクエスト**を渡して (*path operation* によって) 処理させます。
* 次に、ミドルウェアはアプリケーション (の *path operation*) によって生成された**レスポンス**を受け取ります。
* その**レスポンス**に対して何かを実行したり、必要なコードを実行したりできます。
* そして、**レスポンス**を返します。

`yield` を使った依存関係をもつ場合は、終了コードはミドルウェアの *後に* 実行されます。

バックグラウンドタスク ([バックグラウンドタスク](background-tasks.md) セクションで説明します。後で確認できます) がある場合は、それらは全てのミドルウェアの *後に* 実行されます。

We have 3 different things that we synchronize on.

#### Http2Connection

This lock guards internal state of each connection. This lock is never held for blocking operations. That means that we acquire the lock, read or write a few fields and release the lock. No I/O and no application-layer callbacks.

#### Http2Stream
