​The logic you wish imply using a single variable in proxy_cache_bypass
which is set if and only if both $http_cache_control and $_is_get are set.

Does the following ​work?

map $request_method $is_get {
default: "";
GET "true";
}

set $bypass "true"; # Defaults to true

# Each map then deactivates the $bypass variable if one
# of the variables linked with the AND logic is empty
map $http_cache_control $bypass {
default: "";
"": $bypass;
}

map $is_get $bypass {
default: "";
"": $bypass;
}

proxy_cache_methods POST;
​​​​​proxy_cache_bypass $bypass;
