Grant users access only to sites you explicity allow

If you want to have users whitelisted for a few sites, but then block them from everything else
you should use the Blanket Block feature.

Example :

Allow user1 to access yahoo.com and msn.com but deny access to any other website.

In the /etc/dansguardian/bannedsitelist file for the group you are administering,
set the Blanket Block setting as you see below.

#Blanket Block.  To block all sites except those in the
#exceptionsitelist file remove the # from the next line to leave
#only a '**':
**

Now add to the exceptionsitelist the websites that you want people to have access to.
All sites not listed in the exceptionsitelist will be blocked.

(For the example above, /etc/dansguardian/exceptionsitelist file for the group you are administering
should be:

yahoo.com
msn.com
