Openshift Router uses DNS names to perform routing. It is perfectly legal to have this kind of configuration:

client 1 --> example.com:11222 -----+> Hotrod server
                                  /
client 2 --> example2.com:11222 /

In that case the TLS configuration might be problematic (since very often certificates are issued for a domain name). However it is possible to use SNI TLS Extension.

The SNI needs to be added to:

• Client's configuration (it needs to modify it's own SSLContext and add SSLParams
• Hotrod server to support SNI (with Netty)
• XML Configuration for Hotrod
