Caching-only name servers will not have any records of their own. When it recevied a request from a client for the first time it will query on behalf of a client to a nameserver.

no - the caching only name server directly queries the root nameservers on the internet (and of course caches the results). The 'only' refers to the fact that the other elements of a dns server do not run - ie, the machine does not have its own internal dns. bsnl, mtnl and vsnl regularly screw up their dns servers, so it is advisable to run ones own as already suggested
