Leverage browser caching for Nginx, no css when reloading the page
Take a look at Fiddler traces or Chrome dev tools.
A 304 would mean that the server responded with "not modified, use your local cache". If you clear your browser cache or do Shift + Refresh, you will get a 200 along with the body of the file. 304 on the contrary have zero body length.
I was getting the same issue.
Resolved it by placing:
location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ { expires 365d;}location ~* \.(pdf)$ { expires 30d;}inside
location /static/
So the final config looks like
location / { proxy_pass http://app_servers; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ { expires 365d; } location ~* \.(pdf)$ { expires 30d; } }Reference: https://developers.google.com/speed/pagespeed/module/filter-cache-extend
