Bug Description

Hello,

I have to websides running on the same machine, on different ports. With the help of an proxy one of them is reachable under
user.domain.com and the other is reachable under admin.domain.comhost_header_rewrite.

If I set the frpc client now to user.domain.com the tunnel always gets the admin.domain.com page.
I thought I can fix this but manipulating the request header-host with the "host_header_rewrite=user.domain.com" parameter but that shows now effect. In the webrequest the host is still mytunnelsubdomain.tunneldomain.com.

Does I understand the parameter wrong or does he just not work?

Is there another way to get the correct webpage?

frpc Version

0.45

frps Version

0.45

System Architecture

host_header_rewrite is only valid for HTTP, not HTTPS. frp cannot modify content that is encrypted via TLS.

Right, thank you. It works with the https2https plugin and "plugin_host_header_rewrite".
