Add a new check_status value when Cloudflare is in the HEADERS #435
Description
Is your feature request related to a problem? Please describe.
Hundreds of websites in our government are using Cloudflare to protect sites against DDoS. Half the 50k external links end up on Cloudflare protected sites.
Editors seing the general check_status = 3 "not possible to check ("non-checkable")" in BE is not enough. They might think one day the link will be verified which is not true.
Describe the solution you'd like
We want to add a new check_status = 5 for Cloudflare protected websites.
We want to simply check the HEADER of the website since Cloudflare always indicate server: cloudflare to stock the 5 value into check_status and show n the BE module that those links are not possible to check.
