I see. That's a valid point.

Actually, I never considered that one might use HAProxy behind Nginx
in the first place. Rather, I assumed HAProxy would be a more
naturally placed *before* Nginx, if one wanted, say, a more strictly
layered setup where a dedicated proxy did the proxying and a web
server such as Nginx did the static file serving.
