Hi, I know this is an old topic. However, I have installed CentOS7 + CWP (Licenced) with a >>Nginx & Varnish & Apache<< setup.
This is my curl output for HTTP & HTTPS
HTTP/1.1 200 OK

Can someone confirm that this output is OK? How can I test this server-side caching to be 100% sure?
I'm asking this because in both cases I see nginx server. Thought that HTTP is going through Apache and nginx resolves SSL
