Non-delegable client requests to servers storing local information only
are disclosed. In one embodiment, a request is sent from a client to a
server of a list of servers. The server determines whether it is
inappropriate to fulfill the request. If so, it sends an error message to
the client that it is off-line. When the client receives the message that
the server is off-line, it sends the request to another server on the
list, which is continued until a server is found that is able to fulfill
the request. Embodiments of the invention thus leverage existing
client-known error messages to redirect client requests to other servers.
