Probably some combination of <a href="http://nginx.org/r/proxy_cache_bypass">http://nginx.org/r/proxy_cache_bypass</a> and
<a href="http://nginx.org/r/proxy_no_cache">http://nginx.org/r/proxy_no_cache</a>
You may want to change your variable-setting logic; or use a map
(<a href="http://nginx.org/r/map">http://nginx.org/r/map</a>) to make a new $skip_the_cache variable that is
0-or-empty when your $req_has_somecookie is not 0, and has a different
value when $req_has_somecookie is 0, so that you can (e.g.)
proxy_no_cache $skip_the_cache;
in the appropriate location{}s.
