Hi I hope I can get some guidance. I want to have a login link on my webflow website, when the user clicks that link they have to pass through Cloudflare to get to my operational site. I would like to know how to trap the referring webflow IP or Hostname so that I can add this rule to Cloudflare. The basic aim is that if you do not come through the main webflow site you can not access the operational site. Does this make sense? Please let me know of any advice.
