I'm using an Nginx (frontend proxy) + Apache + FCGI + APC setup on my VPS, and W3 Total Cache doesn't seem to generate any configuration files for Nginx.
Does that mean there's no need to configure Nginx to work best with W3TC? Or is it just that W3TC doesn't detect it, thus it doesn't create conf files? If it is the latter version, would this be a good configuration: http://wp-performance.com/2010/10/nginx-reverse-proxy-cache-wordpress-apache/ ?
Cheers!
