I am a teacher with my own web connection for my classroom. I wish to
have ACL's that deal with my morning class differently than my
afternoon class. I have created the rules and applied them, but they
do not seem to be working. I have cleared my cache and restarted
squid but no luck.
Some Background: I am trying to make it so my "am_students" can surf
freely any time before 8:45 and after 10:30. That gives them 1/2 hr
before class starts and 15 minutes at the end to check email, forum
posts etc... At 8:45 I want to limit the sites they visit to those
found in "AM_good_sites.txt" ( entries like .somedomain.com and
.otherdomain.net ...) until 10:30. I have created my timed acl, my
dstdomain acl and my proxy_auth acl. However, it seems that this
config is not working. Any insight would be appreciated.
