Hi all - I have a question from devs about a new cdn subdomain on our site and just wanted to confirm best practices. The entire site, not just images, is duplicated on the cdn.

So:

1. Every url should canonicalize to the main site equivalent.
2. Links to cdn images should canonicalize to their main domain equivalent.
3. The cdn subdomain should not be disallowed or noindexed or anything like that.

Let me know if this all sounds right - thanks!
