Description: Session variables are temporary variables that store data during a user’s session duration in a web application. These variables allow relevant information to be maintained across different web pages, which is essential for creating smoother and more personalized user experiences. In the context of server-side programming, session variables are used to store data that needs to persist throughout the user’s navigation, such as login information, user preferences, or shopping cart contents. Unlike cookies, which are stored in the user’s browser, session variables are stored on the server, making them more secure and less susceptible to tampering. Each session is identified by a unique identifier, which is sent to the user’s browser and used to retrieve session information on the server. This functionality is crucial in web applications where user interaction needs to be remembered, thus allowing for efficient information management and a better user experience.
