在生产环境中，如果我想用负载均衡器搭配 Discourse，是否必须拥有两个域名？

Every time a user enters my site, their request is sent to my load balancer configured on a VPS, this load balancer should send the request to Discourse hosting in the same VPS, and then Discourse responds to my load balancer, but oh wait, the documentation for using Discourse in production says the following:
“Discourse will not work from an IP address; you must own a domain name such as example.com to proceed.”

That means that the clients must access Discourse via a domain name. Internally, behind the last customer facing reverse proxy / load balancer you are can do whatever.
