secondary vs caching

|   In theory, all servers are caching servers. :)

Definitely not. A number of servers are specifically configured *not*
to cache, for instance by using "recursion no" in the BIND 8 options
section. If you also add "fetch-glue no", it won't even cache info
for the Additional section of the answer.
