# =========================================================
# GLKVM Cloud - Reverse Proxy Mode (Nginx Example)
#
# This configuration shows how to run GLKVM Cloud behind
# Nginx in reverse proxy mode.
#
# - TLS is terminated by Nginx
# - GLKVM Cloud listens on plain HTTP internally
# - Web UI and remote device access share the same HTTPS port
# - Routing is based on the requested domain name
