A session is a temporary and interactive connection between a user and a computer system. It starts when a user logs in or initiates an interaction with the system and ends when the user logs out or after a specified duration of inactivity.
Sessions are used to maintain stateful interactions and enable personalized experiences for users. During a session, the system keeps track of user-specific data and preferences, allowing the user to access personalized content or perform actions without repeatedly providing credentials.
Sessions typically involve the exchange of session identifiers or tokens between the user and the system. These identifiers are used to associate subsequent user interactions with the ongoing session. They can be stored as cookies, embedded in URLs, or passed through HTTP headers.
