If you are going to use it inside proxy_no_cache directive, you can
combine proxy_cache_method (POST is not included by default) and
'proxy_no_cache $query_string$cookie__mcnc'
The latter will not cache the request until there is query string or a
cookie with a value set.
So basically, it looks like you can avoid using maps in this case.
