Description:

The SmartProxy package is intended for use in a multi-server setting
where one or more servers may not be directly accessible to client
side scripts. The SmartProxy package makes request redirection and
forwarding on a per class basis easy. Client scripts need not know
which server is appropriate for a specific request and may make all
requests from a single master server which can be relied upon to
redirect clients to the server currently fulfilling a given request.
The relieves a maintenance burden on the client side. The server may
also redirect clients to a new class name or fully qualified action
URI (methods and arguments are assumed to remain constant however).
