How do you keep catalog pages in a frame when you find them

[David Deitz]

We use frames for our shop site. When you find one of our catalog pages in
a search engine and click on the link, you only get that page, not our
frames on the left and top. I assume that each catalog page needs code in it
to see that it is being loaded in a frame, right? Anyone know where to find
that code? I remember seeing code for a page to check to see if it was
being loaded in a frame and if so, make a new window (to keep others from
putting a frame around your pages). I need to do the reverse! Any ideas?!
