nginx doesn't cache json, but caches .jpg file

My nginx server if configured like this:

......
server {
    # Status page
    location /nginx_originserver {
      stub_status on;
    }

    listen 80;

 location ~ ^/1 {
      proxy_pass http://10.10.52.126:1239;
      proxy_cache api_cache;
    }
......
}

In this case, when I browse http://localhost/1/thumbnail.jpg, the image file is cached. But when I change the proxy to a location which returns json like below and browse http://localhost/1/api_service, the json file is not cached, why just the image file is cached but not json, how to cache the json file?

location ~ ^/1 {
  proxy_pass http://10.10.52.126:8090;
  proxy_cache api_cache;
}
Solution

  • Did you try proxy_cache_valid 200 1d;:

    location ~ ^/1 {
  proxy_pass http://10.10.52.126:8090;
  proxy_cache api_cache;
  proxy_cache_valid 200 1d;
}
