A split proxy is configured for managing asynchronous MAPI communications between a client and a server by establishing a queuing structure for MAPI messages that make up the communications. The MAPI messages are subsequently exchanged between the client and the server using the queuing structure. Multiple remote procedure calls (RPCs) underlying the MAPI messages may be grouped together in batches for exchange between proxies of the split proxy. Also, when the client logs off from the server, a MAPI keep-alive process allows updates received at the server to be pre-populated to the split proxy for transfer to the client when it reestablishes a connection.

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.
