	BIND 9.2.1 is old.

	Get the URL fixed, it is broken.

	Dig does not use the search list.

	I'm not sure if Squid uses the systems hostname lookups or
	not.  It would make sence for it to make the lookups directly.

	Anyway make sure that you have restarted Squid after modifying
	/etc/resolv.conf.

	You can setup a zone called "haf0gau05" and populate it
	with the address record.  This needs to be done on all
	nameservers that Squid is using.

	zone "haf0gau05" {
		type master;
		file "haf0gau05.db";
	};
	
	haf0gau05.db:
	$TTL 30
	@ SOA ...
	@ NS ...
	@ A <addres of haf0gau05>

	Mark
