How can I confirm whether I am connected to the correct CDN node?

I am currently working with our application provider to troubleshoot a high-latency issue. To assist with this, the provider has set up a test site and configured a CDN so that we can directly access the closest available node. How can I confirm whether my traffic is hitting the origin server directly or routing through the correct CDN node? Hopefully, the following response header information helps:
