I’ve got a config file like:

http {  
proxy\_cache\_path /var/www/nginx/cache levels=1:2  
keys\_zone=tmpcache:100m;

server {  
location ~ .js$ {  
proxy\_cache tmpcache;  
proxy\_cache\_key $uri$is\_args$args;  
proxy\_pass [http://global](http://global);  
}  
}  
}

However, I’m not seeing any data stored in the tmpcache. No folders  
created, no files. What am I missing?

Without proxy\_cache\_valid nginx will only cache responses which  
explicitly indicate they may be cached (either with Expires header  
in future or with Cache-Control: max-age=).
