Oh right. I think understand what you're saying now. You want the HTTP client 
to somehow detect that it isn't allowed to follow redirects to that target (in 
that manner) and stop because a SOP somehow says so.

How do you suggest that would be told to the client?

Couldn't the TARGET here rather use Referer (or Origin or what not) to detect 
that there's a redirect coming from externally and ignore it?

It clearly can't be HTTPbis material though, since in my eyes it seems to be a 
rather major extension or change of what HTTP is and what it allows today.
