[squid-users] External ACL allowing denied sites

Hi,

Im using a home-made modification of dnsbl_redir for external_acl_type
instead of redirector.

In squid.conf:
external_acl_type dnsbl ttl=60 children=4 %DST %SRC %IDENT %METHOD
/usr/local/bin/dnsbl_redir
acl policy external dnsbl
http_access allow rede10 policy

Here goes the cache.log:

2006/07/05 07:04:05| The request GET http://www.brookeburn.com/ is
ALLOWED, because it matched 'policy'

Resuming, externalAclHandleReply: reply="OK". But when i do:
echo "www.brookeburn.com 10.9.0.10 - GET" | /usr/local/bin/dnsbl_redir
ERR

This site should be denied... What it should be ??
It was working but now started allowing denied sites... uptime is 5
days, i think restarting the server or squid should resolve the
problem... But id like to know what it would be causing this issue.

Regards,
