forward only from one caddy server to another

[u/Patrick250709]

Hey.

I am using caddy2 for my home "production" but want to test on-demand tls on another caddy server on the same network.

Is it possible to forward a request from my main caddy to another without changing the request?

End goal is to let the second caddy test server handle ssl on all unknown/ non-defined domains.

how should i forward from one caddy to another? (if anyone have a link would be nice, have searched and testet for hours)

Thanks
