Abstract

A proxy server receives from a client device a request to perform an action on an identified resource that is hosted at an origin server for a domain. The proxy server receives the request as a result of a DNS request for the domain resolving to the proxy server. The origin server is one of multiple origin servers that belong to different domains that resolve to the proxy server and are owned by different entities. The proxy server and the origin servers are owned by different entities. The proxy server analyzes the request to determine whether a visitor belonging to that request poses a threat. If the proxy server determines that the visitor poses a threat, the proxy server blocks the request and transmits a block page to the client device that indicates that the request has been blocked.
