Hello Jonathan,

Thanks for the reply. I'd love to at least understand the basics, in fact this is what I'm trying to do. It's a bit hard when there's no thorough documentation and all responses found on internet are vague.

You are saying that it will work only when Nginx is a reverse proxy and receives a response from another backend, like Apache. But I want Apache as frontend and Nginx as backend. Should I focus on Xsendfile?
