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.
