No it does not work . It always go through the parent when I enter an
IP URL (http://130.223.27.16) .
The only way I found was to rebuild Squid with --disable-internal-dns.
But it takes some more times in DNS lookups.. and also Squid get
stuck if all dsnservers become busy..
Any idea if that bug is corrected in version STABLE2. ?
