设置仅重定向网址，而不是在iFrame上

Question

I am wondering if I can set a redirect at a URL (This part can be done easily I know v).

But this redirect ONLY actually redirects, when the URL is visited. Not when the URL is displayed within an iFrame .

Can this be done at all? Essentially; Visit said URL with redirect implemented in the header; web page redirects to the defined. BUT, a website using that said URL within a iFrame call, it does not redirect.

Basically a page via URL only really accessible & viewable via an iFrame call.

This is possible via client-side. If you add following code to page onload event:

if (location.href == top.location.href) location.href='http://your_new_url';

the page will redirect to new URL only if it is called as top-level page. If it is called within an IFRAME - the condition will be false and redirect will not happen.
