path of slave server query for external addresses

[rsesnaski at yahoo.com]

I think the answer is that the slave server issues it's own query to
either the
forwarder address or the root servers if it gets a query for a non
local zone
but I want to be sure. So the question is, does the slave query the
master
or the fowarder/root servers for an external address such as
www.ibm.com
assuming I'm not ibm.com of course.
