In a client/server network, a client may be able to use any of several servers in accomplishing a particular task but may still have preferences as to which server should, if available, be used. If the preferred server is not available, the client will be connected to an alternate server. If a server having a higher preference than the alternate server becomes available, state information associated with the client session with the alternate server is used in order to decide when the client may be switched to the preferred server without compromising work currently being done.
