Servlets Tutorial: Introduction to HttpSessionListener | Servlets

Welcome to our tutorial introducing HttpSessionListener in Servlets! In this video, we'll provide you with a comprehensive overview of HttpSessionListener and its significance in Java Servlet technology.

**Understanding HttpSessionListener:**
HttpSessionListener is a Servlet listener interface that allows developers to receive notifications about HttpSession lifecycle events in a web application. This listener interface provides methods that are invoked when sessions are created, destroyed, or invalidated, enabling you to perform custom actions in response to these events.

**Key Concepts Explained:**
We'll start by explaining the purpose and functionality of HttpSessionListener and how it integrates with the Servlet API. You'll learn about the methods provided by this listener interface, including `sessionCreated()` and `sessionDestroyed()`, and how they can be implemented to handle HttpSession lifecycle events.

**Use Cases and Practical Examples:**
Explore practical examples and use cases for HttpSessionListener, demonstrating how it can be used to perform tasks such as:
- Tracking user sessions and activity within the web application.
- Initializing session-specific resources or settings when sessions are created.
- Performing cleanup tasks or releasing resources when sessions are destroyed or invalidated.

**Implementation Guide:**

**Conclusion:**
By the end of this video, you'll have a solid understanding of HttpSessionListener and how it can enhance the functionality and flexibility of your Servlet-based web applications.
