Abstract
A method for storing session state data of a session between a system having a plurality of nodes and a client device includes delivering a service to the client device during a session identified or otherwise specified by a session identifier. The service is delivered by a first of the plurality of nodes in the system. During the session, at least a second node in the system is selected on which session state data associated with the session is to be saved. The second node is selected based on the session identifier such that another node in the system is able to locate the session state data when stored on the second node from the session identifier without contacting a centralized mechanism that specifies where session state data is stored. The session state data is saved to the second node that is selected.
