# This is an example nginx config used to serve your Sandstorm server over SSL/TLS/HTTPS.
#
# Definitions like these should go in the "http" block of your nginx config. Replace "example.com"
# with the domain of your Sandstorm install. On a Debian/Ubuntu system, you can copy this into
# /etc/nginx/sites-enabled/.
# This magic stanza is ESSENTIAL to avoid breaking WebSockets.
#
# Specifically, for WebSocket forwarding, we want to forward the `Connection` header.
# This "map" declaration helps with that.
