Abstract
The present invention provides a method and apparatus for making a computational service highly available in a multiple server computer environment. In the thin client computing paradigm, end user terminals rely on remote server computers for operation of most functions traditionally associated with personal computing. If the remote server computer fails, all of the users' computers will likewise fail. The present invention provides a solution by implementing a redundant server strategy and a redirection process. One or more servers hosting a communication to the terminal do not contain the only copy of permanent user data. This makes all session hosting servers interchangeable. If a server fails, the failure is detected and the terminal switches to another host server.
