Cela comprend, par exemple :

* Les notifications par email envoyées après l'exécution d'une action :
    * Étant donné que se connecter à un serveur et envoyer un email a tendance à être «lent» (plusieurs secondes), vous pouvez retourner la réponse directement et envoyer la notification en arrière-plan.
* Traiter des données :

    }

    /**
     * Handle a witness event
     *
     * @param notification the witness notification
     */
    private void handleWitnessEvent(WitnessNotification notification) {
        log.info("Handling witness event: {} for resource: {}", notification.getEventType(), notification.getResourceName());

        switch (notification.getEventType()) {
        case RESOURCE_CHANGE:

                List<WitnessAsyncNotifyMessage.WitnessNotificationResponse> notifications = message.getNotifications();
                if (!notifications.isEmpty()) {
                    log.debug("Received {} notifications", notifications.size());
                    return notifications.get(0); // Return first notification
                }
            } else {

This includes, for example:

* Email notifications sent after performing an action:
    * As connecting to an email server and sending an email tends to be "slow" (several seconds), you can return the response right away and send the email notification in the background.
* Processing data:

import jcifs.FileNotifyInformation;
import jcifs.internal.NotifyResponse;
import jcifs.internal.SMBProtocolDecodingException;

/**
 * Response for SMB1 NT Transaction change notification.
 *
 * This response contains file system change notifications that occurred
 * in the monitored directory, such as file creation, modification, or deletion.

# Directory Leasing Feature - Detailed Design Document

## 1. Overview

Directory leasing extends the SMB3 lease concept to directories, enabling client-side caching of directory metadata and change notifications. This significantly improves performance for applications that frequently enumerate directories or monitor directory changes.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13.2.12**: SMB2_CREATE_REQUEST_LEASE_V2 for directories
