Blocking banners

I'm trying to deny connections to doubleclick.net, in order to reduce lags
time.
with this :

acl pubs dstdomain doubleclick.net
http_access deny pubs
deny_info blank.html pubs

Of course, the connections are denied, but SQUID print out an error message.
Even with my own error message blank.html, a line is added and printed like

Generated Tue, 31 Aug 1999 15:05:28 GMT by proxy (Squid/2.2.STABLE3)

How can we avoid errors output ? I want it to be quiet.

Thanks for the help out there.
