Hello Cloudflare community, in my agency (crececonseo.com), we are using the service for quite some time to improve the security of websites and facilitate some tasks.
I am currently trying to redirect from one domain to another in both their http and https versions without hosting. As I understand through a page redirect it should work but I am not getting it.
You should should “Full (strict)” to ensure the connection from Cloudflare to your origin is encrypted (at a minimum, use “Full” if strict gives problems while you fix them) - but that won’t affect the page rule which is between the client and Cloudflare (unless your origin doesn’t support HTTPS in which case things will break).
