Abstract

A method, apparatus and computer program product for providing failover capability of cached secure sessions is presented. A cached secure session involving a first device and a second device is identified. The cached secure session is encrypted and replicated to a failover device. The encrypted session is then decrypted on the failover device. An occurrence of a hot failover involving the second device is detected, and processing resumes between the first device and the failover device.
