Do you know how I would allow access based on the referer? I'm
searching for how to do this and would like to try it out.

I'm using squid 2.6 and have it configured to block all websites

several sites that are fine to access, such as kbb.com, have content
invoked from other sites. So when I view kbb.com for example, the
page
is missing most it's content and looks really messed up in firefox,
and this happens with other sites. Is there some way to allow access
to approved sites, and further sites that are invoked?
There's no easy way for squid (or any proxy, really!) to properly
determine "and further sites that are invoked."
You could possibly allow access based on referrer URL as well - which
should show up as having been referred by your list of approved URLs -
but referrer URLs can't be trusted as anyone can just fake them.
