I am trying to set up a proxy server that does the following, and I'm not
even sure where to begin.
Basically, the server needs to do these two things:
1. One class of authorized users who have unrestricted access to the
Internet.
2. A second class of users who are denied access to the Internet, except
for a predetermined whitelist of sites that they need to be able to
access. Basically, we want to do site-filtering rather thatn
content-filtering.
Is this even possible with e.g. squid, or do I have to look someplace
else?
