My client goes from
(register) Godaddy to CloudFlare (DNS) to my server at WPengine.
Here are my questions.
1. Does CloudFlare simply index and cache the site to get page for their CDN?
2. Without the WP CloudFlare plugin, will CloudFlare still work without the server connecting to it or does having the DNS go to it enough? I guess this goes back to question 1.
3. Is it it a good idea to have 2 CDNs running, one from CF and the other from the host?
Anything else that you think I need to know would be helpful.
