How non-solicited sites are blocked is not known to me. I do know we do not have the ability to
access (read) our internal e-mail from outside (at least yet).

For solicited sites, if I correctly understand the way our IT guy has done it, all blocked URLs are
done so by specific IP address. Everything (as in all) done by any computer on campus is looked at
by the server(s). All web site URLs are logged. High traffic sites (number of students or long
connect times) are investigated. If they are an objectionable site that URL is added to the list.
The server will not connect to the listed addresses. (This has turned out to be a better method
than using blocking software. We had trouble with newspaper and periodical sites being blocked.
This way we let the kids "tell us" which sites we should ban. Even non-objectionable game sites get
blocked if they are used too much during school hours.)

All most everything is supervised by the servers (there are 4 of them). Even printing. All
printers are network printers but the server even watches over that function. For instance,
students are not allowed to make multiple copies on a print run. If they try to print say 10 copies
(per print run) the server reduces it to one.
