Force cache on files with Nginx

Question

I am trying to force the cache of this type of files: css, woff, otf, js, jpg, jpeg, gif, png, ico, cur, gz, svg, svgz, mp3, mp4, ogg, ogv and files without extension.

I can cache some images and mp3 files, but the rest are always in a state: X-Cache MISS

proxy_cache_path /tmp/test keys_zone=test:10m loader_files=300 max_size=4g;

location ~* (^/.*(css|woff|otf|js|jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp3|mp4|ogg|ogv)$|^/web/image.*) {
          proxy_cache test;

          proxy_cache_methods GET HEAD;
          proxy_cache_lock on;

          proxy_ignore_headers Set-Cookie;
          proxy_ignore_headers X-Accel-Expires;
          proxy_ignore_headers Expires;
          proxy_ignore_headers Cache-Control;

          add_header Pragma "public";
          add_header Cache-Control "public";
          add_header X-Cache $upstream_cache_status;
          access_log off;
          expires 12h;

          proxy_pass http://test;
  }

GET:

• Accept: text/css,/;q=0.1
• Accept-Encoding: gzip, deflate, br
• Accept-Language: es-ES,es;q=0.8,en-US;q=0.5,en;q=0.3
• Cache-Control: no-cache
• Connection: keep-alive
• DNT: 1
• Pragma: no-cache

Nginx:

• Cache-Control: max-age=43200
• Connection: keep-alive
• Content-Encoding: gzip
• Content-Type: text/css
• Date: Fri, 15 Dec 2017 10:20:22 GMT
• ETag: W/"XXXXXXXXXX"
• Expires: Fri, 15 Dec 2017 22:20:22 GMT
• Server: nginx
• Transfer-Encoding: chunked
• Vary: Accept-Encoding
• X-Cache-Status: MISS
• X-Content-Type-Options: nosniff

Try to add

proxy_cache_valid 200 1d; 

to keep all files matching your location that have a http state of 200 for 1 day in cache
