Stateful Connections
Stateful connections are network connections where the server maintains information about the client's state across multiple requests, enabling persistent interactions. This contrasts with stateless connections, where each request is independent and the server doesn't retain client context. Common examples include TCP connections, database sessions, and web application sessions that track user login status.
Developers should use stateful connections when building applications that require continuous interaction, such as real-time chat systems, multiplayer games, or financial transactions where maintaining session data is critical. They are essential for scenarios needing persistent data exchange, like streaming services or applications with user authentication, as they allow servers to remember client context and provide personalized responses.
