[Zope] how to tell if displayed in a frame

I have a page that sometimes gets displayed in a frame and sometimes in the main window. I want it to be display differently (with a header) when its not in a frame. Is there a way I can do this? I don't suppose the name of the target frame gets passed to the browser does it? Presumably the only way to do this would be to do it in client-side code and fecth the header if appropriate and filter it to make it what is needed. Or is it?
