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.
