The most basic options are:

- You can set Expires from your backend as desired for browser 
  caching, and use the X-Accel-Expires header to set caching time 
  for nginx (see http://nginx.org/r/proxy_cache_valid).

- You can configure nginx to ignore Expires and Cache-Control as 
  set by your backend (see http://nginx.org/r/proxy_ignore_headers), 
  so these will be used only by browsers, and set caching time for 
  nginx manually with proxy_cache_valid (see 
  http://nginx.org/r/proxy_cache_valid).
