[squid-users] Redirecting certain sites with a forward option?

I have a few teachers how want a group of students to be forwarded to
a page for certain sites. The page would then have forwarding option
to view the original site. They are trying to add around 100 URL's to
this list. For example, if student tries to access loc.gov site, they
would be redirected to our page that would have some guidelines
written by teachers, and on the bottom of that page student could
click on "Continue to original address, %URL.

Squid v 3.1.6 is setup in transparent mode.

Is this possible?

Here is our config file:
