Abstract: Techniques are presented herein for redirection between any number of network devices that are distributed to any number of sites. A first message of a flow is received from a network endpoint at a first network device. A relationship between the endpoint and the first network device is registered in a directory that maps endpoints for network devices. A state for the flow is stored at the first network device. A second message is received for the flow which is indicative of the first endpoint at a second network device. It is determined that the second network device does not store the flow state for the flow. Querying is performed to receive information indicative of the relationship between the endpoint and the first network device. The received information is stored in a cache at the second network device. Services are applied to the second message according to the stored information.
