I have a website with lots of images. I have setup a CDN to store the images in Cloud and am using a CDN Subdomain to map the Cloud server url to display the images on my website.
Since the Subdomain is Virtual, there is no physical robots.txt file to help me disallow indexing by bots.
How do i disallow the bots from indexing the Subdomain.
Primany domian : www.mysite.com
Virtual Subdomian for CDN purpose : images.mysite.com
I want to disallow indexing of images.mysite.com
