What is Request Control?
The Request Control Cloudlet allows you to provide conditional access to your website or application by defining and managing whitelists and blacklists based on a number of match criteria, including the IP address and/or geography associated with incoming requests. In addition, you can have a branded 403 (Forbidden) page display when a user is denied access.
The default for Request Control is to give access to all requests. You use your rules to restrict access.
