+In the quest for speed, we are going to tweak several settings in nginx. To
+keep things manageable, most of those tweaks go into separate configuration
+files that are either automatically included (those under `/etc/nginx/conf.d`)
+or explicitly where we need them (those under `/etc/nginx/snippets`).

+For every `proxy_forward` we want to configure several settings, and because
