It is possible that Cloudflare sends a Header for example called “mobile” with yes / no. To show different content if the client is from a phone or PC? We have already resolved with the user-agent to detect the device, but we can not send this information to the “Origin”.
Cloufront (Amazon) has a Header called “CloudFront-Is-Mobile-Viewer” that allows you to make two different cache copies according to the device.
Is there a similar function in Cloudflare?
