How can I enable node.js proxy for websocket on OpenShift?

I have a problem with openshift proxy for websocket.

I read here:

that on client for web socket I can use the port 8000 or 8443 guaranteed from a nodejs proxy but my applications don't have open these ports.

I have a silver plan and I have two application, one with wildfly and one with node.js and none work.

Can anyone help me?
