I don't know about with reverse proxy, or the version on the IBM i, but with my linux hosts SNI just works. I set up multiple virtual hosts and inside each of them point to the respective certificate, and each site serves the correct cert.

Yeah...I saw SNI referred to in many "generic" Apache posts but I couldn't
find documentation about it for IHS for IBM i. *Just* found the 7.2 HTTP
Server for IBM i Redbook so I'll peruse that and it does specifically state:

Server Name Indication(SNI) is an extension to the SSL and TLS protocols that
indicates what hostname the client is attempting to connect to at the start of
the handshaking process. This allows a server to present multiple certificates
on the same IP address and port number and hence allows multiple secure
(HTTPS) websites to be served off the same IP address without requiring all
those sites to use the same certificate. It is the conceptual equivalent to
HTTP/1.1 virtual hosting for HTTPS.

I hope there is a *good* example of a working configuration......

Once done, if done, I'll post up the working config so you won't have to
experiment as much as I have....

I've tried this in the past without luck. But that was before the
apache server was able to use SNI. I haven't tried since as I want my
sites to be up. Maybe one weekend I'll give it another shot.:)
