ABSTRACT:
A method and apparatus for policy management in a network intermediary device. One embodiment of the invention, includes establishing a session between a client and an intermediary device on a network to enable processing of a communication between the client and the intermediary device. Then, the communication is processed by the intermediary device while maintaining a consistent version of policy throughout the communication. Finally, after the communication is complete, the intermediary terminates the communication. The intermediary device may maintain consistent policy by utilizing a policy ticket upon which transactional information is stored and that references the version of policy that was current when the communication first began. The policy ticket may be transported throughout the intermediary device according to a “checkpoint” scheme, and at each checkpoint, evaluating the policy rules, if necessary, to determine appropriate actions to be taken based on current client and network information as applied to the policy rules.
