I’d like to use CloudFlare just for server switching, e.g. pointing a domain from one server to another quickly? I know that can be done, but also I would need to turn off all caching and also be sent the users’ real ip addresses. The reason being we use membership software that in turn uses Stripe for billing and we need to verify the country users are in to set tax rates (using ip address). We can’t change membership/billing software so ip address has to appear in the “normal” place. Is this possible?
