Dedicated IP: X-Forwarded-For Support

We've added X-Forwarded-For support to our Dedicated IPs to enable a middleware proxy to forward the client's IP.

This can be especially useful when using redirect.pizza as a headless redirect provider, where the redirect is executed within the CMS or CDN layer, powered by the powerful redirect.pizza matching engine. Passing along the correct client IP will result in a better analytical overview and the ability to steer traffic based on IP information, such as country.
