摘要： A computer-implemented method includes receiving, at a service running on the hardware, invalidation information relating to one or more resources; and determining whether the invalidation information relates to any resources currently stored on the service. Based on the determining, when the invalidation information relates to at least one resource not currently cached on the service, maintaining on the service at least some of the invalidation information; and using the maintained invalidation information on the service to prevent subsequent use of a version of at least one resource not currently stored on the service.

摘要： A computer-implemented method in a content delivery (CD) network includes determining at least one pseudo client IP address using first log information and second log information. The first log information being from a rendezvous service in the content delivery (CD) network, and includes at least one resolver IP address associated with at least one first request made at the rendezvous service. The second log information is from at least one probe service in the CD network, and includes at least one client IP address associated with at least one second request to the at least one probe service. The method also includes making an association between (i) the at least one pseudo client IP address and (ii) the at least one resolver IP address; and then, responsive to a name resolution request, the name resolution request including the at least one resolver IP address, the rendezvous service using the at least one pseudo client IP address instead of the resolver IP address to resolve the name.

摘要： A computer-implemented method is operable in a network comprising multiple delivery service endpoints running on a plurality of devices where each of the delivery service endpoints is constructed and adapted to deliver resources. A plurality of the delivery service endpoints comprise a group, wherein each node in the group has at least one kind of responsibility relating to delivery of resources. The method includes receiving a request at a node; and, based on what kind of responsibility the node has for the request, attempting to process the request outside the group.

摘要： In a content delivery framework including a network with multiple delivery service endpoints running on devices, the multiple service endpoints forming a plurality of sub-clusters, a group is defined from a set of nodes comprising delivery service instances across the devices of the plurality of sub-clusters. Each node in the group assumes one or more discrete responsibilities involved in processing of a request across the group, the discrete responsibilities including being fill-responsible. A fill-responsible node is selected from the group to be responsible for processing a request made at a node of the group, the request relating to a particular resource. Selection of the fill-responsible node is based on the particular resource, and the fill-responsible node is selected from a set of one or more nodes in the group that are fill-responsible for the particular resource, the set being defined based on a policy associated with the particular resource.
