Abstract
A method and an apparatus for routing network messages from a client to a server bypassing a router which requires that the router, in one embodiment, maintain a table to record where the client's communications were redirected in previous communications. This allows the router to reestablish an identical connection the next time the client needs to communicate with a server. Further, the router transmits a multicast message containing the redirection information to the other routers in the system allowing the other routers in the system to reestablish the same client-server connection.
