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.
