It looks like you want to bypass the cache (and therefore always serve
these requests from upstream), for certain requests.

Is that correct?

If so -- you must set the "$no_cache" variable based on something in
the request, not on something in the response like a $sent_http_ variable.

Perhaps try setting $no_cache based on $request_uri or $document_uri? That
might fit three of the four above.

(Alternatively: set $no_cache to 0 by default, and to 1 based on requests
that you are happy to potentially have served from the cache.)

Good luck with it,
