So I should treat tcp tunneling through https port to backend server the way same as regular https backend server, Joost? I do have SSLProxyEngine on statement. Thanks.

You need SSLProxyEngine on, and then ProxyPass / https://backend/ (the ProxyPassReverse line is probably unnecessary because it's not https-traffic, but it won't kill you to add it anyway).
