It won't, actually, nor should it. The cost of the network traffic to
restore the cache for the sites you visit often should be small. Sites
you don't visit often should be looked up again anyway.
The original poster should look at configuring his nameserver as a
forwarder (not forwarder only) so that he can take advantage of his
ISP's resolver instead.
