Hybrid Session Management via Cookie-Server Transition

The patent segments session management into two parts: session validation logic remains on the server (improving reliability), while session data is distributed across multiple data centers and can be stored in various locations including client devices (improving scalability). This allows the system to maintain security and control while distributing the burden of managing concurrent sessions across multiple locations rather than concentrating all session data in a single server.

The patent introduces session tokens as an intermediary mechanism. These tokens are generated by the server and stored in cookies on client devices, allowing scalable client-side storage while maintaining server-side validation capability. The tokens act as a bridge between the client and server, enabling the server to validate sessions without storing all session data centrally, thus resolving the contradiction between scalability and validation capability.

The patent applies local quality by allowing different session management approaches for different users and different data centers. Not all users require full server-side session management; instead, the system dynamically determines which users need server-side validation based on their specific needs and the security requirements of the applications they access. This reduces overall server resource consumption while maintaining necessary control features where required.
