Problems with cache by mime/type

[Jorge Pereira]

Hi,

I am using the nginx/1.12.0 and I am trying to use the below config.
but, the below "map" by "$upstream_http_content_type" is always
matching with default value "1". but, if I remove "proxy_cache_bypass"
then the map it works. therefore, I need the "proxy_cache_bypass "
capability.

http {
  include       /etc/nginx/mime.types;
  default_type  application/octet-stream;

  map $sent_http_content_type $no_cache {
    default                   1;

    application/zip           0;  # *.zip files
    application/octet-stream  0;  # /artifactory/api/pypi and any
other binary files.
    application/java-archive  0;  # *.jar
    application/x-nupkg       0;  # /artifactory/api/nuget/.*/Download/.*
  }

  proxy_cache_path $CACHE_FOLDER
                   levels=1:2
                   keys_zone=artifactory_cache:$CACHE_KEYS_SIZE
                   max_size=$CACHE_SIZE
                   inactive=$CACHE_DURATION
                   use_temp_path=off;

  server {
    listen 80;
    server_name mywww.lan;

    set $upstream https://172.16.0.1/artifactory;

    proxy_read_timeout  10;
    proxy_pass_header   Server;
    proxy_cookie_path   ~*^/.* /;
    proxy_next_upstream http_503 non_idempotent;
    proxy_set_header    Host  $http_host;

    proxy_cache               artifactory_cache;
    proxy_cache_bypass        $no_cache;
    proxy_no_cache            $no_cache;

    add_header X-Proxy-Cache  $upstream_cache_status;

    proxy_cache_key      $scheme$proxy_host$request_uri$auth_cache_key;
    proxy_cache_valid    200 24h;
    proxy_ignore_headers "Set-Cookie" "Cache-control";

    location ~/mypath(?<relative_uri>.*)$ {
      proxy_pass $upstream${relative_uri}${is_args}${args};
    }
  }
}
