I have my system running in OpenShift 3.11.
I have to implement an https/REST integration with a legacy Java 1.6 system, which supports SSLv3 only.
Thus I had to enable SSLv3 encryption on my web server and I'm using passthrough mode for my OpenShift routes.
When I'm running openssl s_client -connect localhost:4430 -ssl3 inside my pod's terminal to test SSLv3 connection, everything's fine:
CONNECTED(00000003)
Can't use SSL_get_servername

Yes, got a confirmation from a team that managed OpenShift in my organization that HAProxy was blocking SSLv3.
