### 5.2 Session Integration

// In SmbSession.java
private DirectoryLeaseManager directoryLeaseManager;

public void initializeDirectoryLeasing() {

この場合、レスポンスの送信が終わるまでデータベースセッションが保持されますが、使わないのであれば保持する必要はありません。

次のようになります:

{* ../../docs_src/dependencies/tutorial013_an_py310.py *}

終了コード、すなわち `Session` の自動クローズは:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[19:21] *}

...の部分で定義されており、遅いデータ送信が終わった後に実行されます:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[30:38] hl[31:33] *}

    * Normalmente, un token se establece para que expire después de algún tiempo.
        * Así que, el usuario tendrá que volver a iniciar sesión más adelante.
        * Y si el token es robado, el riesgo es menor. No es como una llave permanente que funcionará para siempre (en la mayoría de los casos).
* El frontend almacena temporalmente ese token en algún lugar.
