The TLS handshake initiation contains the requested domain in cleartext, to allow a server to select the correct certificate. Therefore, the server should be able to proxy the handshake, and all subsequent packets, to the correct domain/machine/server, without performing the authentication. Therefore, it should not need any certificates to perform this proxying. This would come in handy when there are a couple of servers in the local network, each serving one domain.
My question is: is it possible to configure apache(2) to proxy incoming requests, over a HTTPS connection to the correct domains, without it having access to the certificates for said domains?
