Abstract
Described is an improved approach to ensure high availability for established sessions (e.g., application layer sessions) over network connections that negotiates and renegotiates encryption keys (e.g., TLS/SSL) at clean boundaries to ensure in-transit data are properly handled during migration of an application (e.g., a reverse proxy server instance). Connected TCP sessions may be handed off to another application (e.g., from existing proxy server to new/upgraded proxy server) and after establishing a new TLS session with a new encryption key, data transfer may be resumed between a client and a server using the new/upgraded application in a client-server architecture.
