We have nginx running, and for reasons I don’t understand, it seems to  
be caching content to /var/lib/nginx/proxy. I can’t even find this  
setting in the configuration anywhere, i.e. the following returns  
nothing:

root@lb01:/etc/nginx# find /etc/nginx | xargs grep “/var/lib/nginx”

We have the following set:  
proxy\_no\_cache 1;  
proxy\_cache\_bypass 1;

I have pasted our config to [##### File /etc/nginx/nginx.conf:user www-data;worker\_processes 4;pid /var - Pastebin.com](http://pastebin.com/w7E0trG6). If anyone has  
any ideas why nginx is caching, it would be appreciated.

Doug.

I would rather suggest it’s proxy temporary files, not cache. If  
you don’t want nginx to buffer responses to disk, use  
proxy\_max\_temp\_file\_size directive. See here for details:
