Redirect PDF to ensure PDF within frames?

My website currently uses frames. The left frame contains important
information that needs to be displayed along with the right hand frame
which contains a pdf or djvu files. See
http://www.campusview.com/schools.ph...=ucla&type=pdf as an
example. Everything works well with this setup. The issue I have is
when Google directs people to the PDF from a search, the user only
gets the PDF, not the frame. Thus they don't get the information that
our business clients are counting on us to show the users.

Does anyone know how to set up a redirect in Apache so that when a pdf
is requested from the server it will redirect to the correct frameset,
without going recursive since the pdf still needs to be displayed?

In other words:
1. A user searches for UCLA and Goolge sends them to
"http://www.campusview.com/schools/ucla/pdf/ucla.pdf"
2. The server redirects to
"http://www.campusview.com/schools.php?cvname=ucla&type=pdf"

Thanks for any guidance!
