title: What are the domains for CORS requests from AMP?
body: <p>I am new to AMP and have questions about how it uses CORS requests.</p>
  
  <p>In reading up on this topic, (<a href="https://amp.dev/documentation/guides-and-tutorials/learn/amp-caches-and-cors/amp-cors-requests" rel="nofollow noreferrer">https://amp.dev/documentation/guides-and-tutorials/learn/amp-caches-and-cors/amp-cors-requests</a>),
  and I see some info for handling requests for CORS-specific origins, namely cdn.ampproject.org and amp.cloudflare.com.</p>
  
  <p>So if I owned foo.com, for example, I would need to handle foo-com.cdn.ampproject.org and foo-com.amp.cloudflare.com, and so on for any number of domains I might be implementing this on.</p>
  
  <p>Are there other domains like the ampproject cdn and cloudflare that are common for the AMP project?  I have not seen too much detail on other domains but now that I see Bing is also involved with AMP I think there may be others.  I wondered if there's a list or common repository for such info?</p>
