Abstract
Techniques for managing session data in a computer system having a plurality of servers establishing sessions with clients. Communications from any particular client are forwarded to the server assigned to handle that client. A load balancer may determine that any particular session for any particular client should be moved between servers, based on load balancing criteria. In this case, the load balancer causes session data for the server assigned to the client to be transferred to a different server. Acknowledgment signals are sent between the servers and load balancer to indicate completion status. Load balancer maintains backup data at secondary servers which can be brought online when a primary server becomes unresponsive. A method, system, and computer-readable medium are provided.
