Transferring Designs with Socket.io

It's imperative that we figure out how to transfer designs between the client and host applications as soon as possible. This is crucial to the core functionality of our installation.

It would be easy enough to simply use POST requests at a specific port on the server to send information from one application to another. The problem with this is that POST requires the page to be reloaded and our host application needs to update in real time.

From what I understand, using sockets seems to be a good way to transfer data in real time. After doing plenty of research I still haven't been able to find information on how to use sockets to send data to a specific port. I'll need to get some help on this.
