yes it will; but you dont have to reboot the server; try:

rndc flush

or just restart bind

	Thanks. But actually, I did not want it to flush cache on restart. In fact I wanted it to keep the cache as long as possible, unless I said `rndc flush`. :-) – Akilan Sep 2 '11 at 6:48
	Is there an option to prevent flushing cache on restart? – Akilan Sep 2 '11 at 7:52
	@Akilan - you can dump current cache with rndc dumpdb ; but i dont think it's possible to reload such data [ see here lists.isc.org/pipermail/bind-users/2002-November/042297.html ] – pQd Sep 2 '11 at 8:55
