Enable Full site accleration in cloudflare

[Pravi (PK)]

In order to enable full site acceleration on Cloudflare,

1. An A record named origin (or any name) has to be created such that origin.mydomain.com is proxied by Cloudflare and mydomain.com resolves to my Linode IP.
2. force_https must be disabled in my Linode server.
3. SSL/TLS encryption mode in Cloudflare should be Flexible.
4. Always Use HTTPS has to be turned off in Cloudflare.
5. Set http://origin.mydomain.com as long polling base url in settings
6. DISCOURSE_ENABLE_CORS: true has to be added in the app.yml

Can anybody confirm this?
Thanks in advance.
