    Abstract: A proxy server receives from a client device a request for a network resource that is hosted at an origin server for a domain. The request is received at the proxy server 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 transmits the request to the origin server. Responsive to determining that the origin server is offline, the proxy server determines whether the requested resource is available in cache. If it is in cache, the proxy server retrieves the requested resource from the cache and transmits the requested resource to the client device.

    Abstract: A first packet of a first protocol version type that includes an incoming request for an action to be performed on an identified resource is received from a client at a proxy server as a result of a DNS request resolving to a network address of the proxy server. The proxy server transmits an outgoing request for the action to be performed on the identified resource to a network address of the destination origin server in a second packet that is of the second protocol version type. The proxy server receives a third packet that includes an incoming response from the destination origin server, the third packet being of the second protocol version type. The proxy server transmits a fourth packet to the client, the fourth packet being of the first protocol version type, wherein the fourth packet includes an outgoing response that is based on the incoming response.

    Abstract: A near end point of presence (PoP) of a cloud proxy service receives, from a client device, a request for a network resource. A far end PoP from a plurality of PoPs of the cloud proxy service is identified. Responsive to determining that a version of the network resource is stored in the near end PoP, a request for the network resource is transmitted to the far end PoP with a version identifier that identifies that version. The far end PoP receives, from the near end PoP, a response that includes difference(s) between the version of the network resource stored in the near end PoP with a most current version of the network resource. The response does not include the entire network resource. The near end PoP applies the specified difference(s) to the version that it has stored to generate an updated version of the network resource, and transmits it to the client device.
