The protocol operates against a protocol server that is identified by a URL that is known by protocol clients. The protocol server endpoint is formed by appending "/_vti_bin/cellstorage.svc" to the URL of the protocol server. An example is http://www.contoso.com/_vti_bin/cellstorage.svc.
The protocol assumes that authentication has been performed by the underlying protocols. Authorization is dependent on the storage mechanisms of the protocol server and is not defined by this protocol.
