The site I pointed to uses JavaScript to highlight your current position
in the site, by swapping images. The cross-frame js code is used to keep
the highlighting in sync with the content frame, even when using
hyperlinks that take you to a idfferent section of the site, or when you
are using your browsers history function.

When a visitor with JavaScript switched off visits the site, navigation
still works. Only the highlighting will cease to support visitors in
keeping tab on where in the site they are.
