nginx is not caching anything. Every request that’s supposed to be  
cached  
has “http cacheable: 0” in debug log.

Test request is a static page with headers like those

\< HTTP/1.1 200 OK  
\< Date: Tue, 17 May 2016 12:23:36 GMT  
\< Server: Apache/2.2.15 (CentOS)  
\< X-Powered-By: PHP/5.5.32  
\< Content-Length: 5  
\< Connection: close  
\< Content-Type: text/html; charset=UTF-8

Can you please suggest anything?

You need to configure proxy\_cache\_valid for nginx to cache such a  
response, see [Module ngx\_http\_proxy\_module](http://nginx.org/r/proxy_cache_valid).

It was already set but apparently wasn’t being used.

location /static/ {  
try\_files $uri @apache-cache;  
proxy\_cache\_valid 5m;  
}

location @apache-cache {  
…  
proxy\_ignore\_headers Set-Cookie Expires Cache-Control;  
proxy\_hide\_header Set-Cookie;

```
internal;

```

}

Moved this directive to second location and now it’s all fine.

Thanks!
