## Intent of Client Session Design Pattern
The Client Session design pattern aims to maintain a user's state and data across multiple requests within a web application, ensuring a continuous and personalized user experience.
The Client Session design pattern is essential for web development involving client-server interactions. It aims to maintain a user's state and data across multiple requests within a web application, ensuring a continuous and personalized user experience. This pattern helps in creating a seamless user experience by managing user state and data effectively across different sessions, crucial for modern web applications.

> The client-server model on Wikipedia describes a system where client devices request services and resources from centralized servers. This model is crucial in web applications where client sessions are used to manage user-specific data across multiple requests. For example, when a bank customer accesses online banking services, their login credentials and session state are managed by the web server to maintain continuity of their interactions.
