[squid-users] Proxy restricted access acl's not working all of a sudden

Hey list,

All of a sudden some of my acls isn't working. I'm running Dansguardian
2.8.0, Squid 2.5, and webmin 1.23 on Fedora Core 2. I created (3)
acls. I work in a youth center, and I needed to restrict access to a
website during certain time periods. (2) of the acl's are date and time
acl's. The first acl is for monday, tuesday, thursday and friday for
times 4pm through 6pm. The 2nd acl is for wednesday from 2pm through
6pm. The 3rd acl is a URL regexp for the specific website that I want
to restrict access to. My first proxy restriction specifies that I deny
the urlregexp I created for wednesday, and then the 2nd proxy
restriction denies the urlregexp for the rest of the week during those
time periods. The line after that allows my network, then allows
localhost and then ends with deny all. Now, this has all been working
for 2 weeks. Now I find that the youth are able to browse the
particular website I wanted blocked during the times that the acl should
be restricting them. I have my browser configured to use the proxy as
well so that I can test whether or not the proxy is working or not. And
yes, I can browse the same site from my browser during the time that
site is supposed to be restricted. I didn't make any changes to the
acl's or proxy once I got it working 2 weeks ago. I'm the only
sysadmin, and no one else has access to the servers. Any ideas?

Thanks,

David
