Following nginx configuration in a server block can cache js and css  
files  
with “js” or “css” as the end of the url.

```
    location ~ .*\.(js|css)?$ {
            expires 7d;
            }

```

But it can’t cache request such as:

http: [//example.com/jquery.js?ver=1.11.3&build=1](https://example.com/jquery.js?ver=1.11.3&build=1)

or

http: [//example.com/style.css?ver=4.3&build=1](https://example.com/style.css?ver=4.3&build=1)

Any way to cache cs/jss files above? Or cache files based on the file  
type  
of request instead of file name?

Please try to remove $ in the end of the expression:

something like this:

location ~ .\*.(js|css) {  
expires 7d;  
}

Also, make sure you are using args in the cache key:

proxy\_cache\_key “$host$uri$is\_args$args”;

Well, unfortunately this is not working…

You will need to be a little bit more specific than ‘this is not  
working’  
to get some help.

## Btw, the documentation show the default value for proxy\_cache\_key if none is provided, and it already takes arguments (and thus arguments’ separator) into account: [Module ngx\_http\_proxy\_module](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_cache_key) [Module ngx\_http\_core\_module](http://nginx.org/en/docs/http/ngx_http_core_module.html#var_request_uri)
