Is there a possible duplicate content penalty for a site using a CDN?

Hi there,

I have recently set up W3TC on my WP blog to use Amazon Cloudfront.

I created 10 subdomains and my website is now screamingly fast. However, when I type any one of those subdomains into my browser I can see my entire website. Clicking any link returns me to my primary domain.

I typed the subdomain addresses into Google and lo and behold, Google lists my pages but only shows the primary domain.

For some reason 2 of the subdomains show absolutely no results in Google.

What are your thoughts about duplicate content being served by these 10 subdomains? Can I fix this with robots.txt?

I am quietly freaking out about this.

Google handles the Amazon Cloudfront CDN (and other major CDNs as well) with no problems. You can relax the quiet freak out ;)

Just when I thought I had picked a bad day to give up sedatives you chime in with some sage advice.

Thank you Tedster. :)
