Yes, that will work, but it will require https termination in the remote server.

If frps could multiplex based on SNI, It could helps some users that have high concerns for privacy while at the same time helps in saving some bucks by avoiding to need to buy additional Public IP if they choose to for example use port 443 for all of their service which might be deployed in more than one unexposed private machine.

https proxy in frp is just a sni proxy. It will only read servername and passthrough traffic to your client.

oh you mean vhost_https_port ? i was thinking about deploying https proxy in front of frps.

let me check first

oh by the way, how do you specify multiple domains in custom_domains ? is it comma separated?
