How is Squid knowing when to redirect and when not?

I suspect you created yurself a redirection loop, where the frame
contents again gets redirected to the frame set.

To use frames in this manner you need something which actively rewrites
HTML and inserts javascript detecting if the page is run within a
frameset and reloads via the frameset if not. A simple url rewriting
proxty can not do the job as it is not visible at the HTTP level if the
request came from within a frameset or standalone.
