[squid-users] ACL not displaying Custom Error page

I have been writing some acls in squid to deny access to various sites
during working hours. It all seems to be working well but I would like
to display a custom error page instead of the standard access denied one.

I have created the page in /etc/squid/errors/ and added the deny_info
line but still get the standard page.

Can anyone shed any light?
