如何将包含NodeJs模块的Codeigniter应用程序部署到Bluemix？

I'm currently working on a codeigniter application with some nodejs for some real time features, i integrated the nodejs module to develop a real time chat application using socket.io and express. I tried to deploy my app to bluemix using a php build for my codeigniter app and i created a nodejs app to host my nodejs server. the problem is i can't seem to connect to the nodejs server socket using io.connect(). is there any way to do so without having to make some major changes in the code. thanks.I'm currently working on a codeigniter applicat
