Abstract: A computer-implemented method, in a content delivery (CD) network that delivers content on behalf of multiple content providers. The method includes, at a server in the CDN, wherein the server is currently processing at least one other request in at least one other session: receiving a connection request from a client, the connection request being associated with a corresponding content request; determining whether handling the content request will cause the server to become overloaded; and, based on the determining in (B) and on information about the content request, conditionally (i) accepting the content request, and (ii) terminating or throttling at least one session on the server.

Abstract: A computer-implemented method includes receiving, at a service, invalidation information relating to at least one resource. Based on the invalidation information, a staleness trigger of the at least one resource is set as a function of an invalidation period. The at least one resource is considered to be not useable based on the function of the invalidation period and the staleness trigger.

Abstract: A server in a content delivery (CD) network that distributes content on behalf of one or more subscribers. Responsive to a request from a client for a particular resource, if the particular resource is already in a cache on the server, serving the particular to the client from the cache; otherwise if the particular resource is not already cached on the server, when a count value exceeds a first threshold value, obtaining, caching, and serving the particular resource. When the count value is less than a second threshold value, obtaining and serving the particular resource. When the count value is: (i) not less than the second threshold value, and (ii) not greater than the first threshold value, then obtaining the particular resource and selectively caching the particular resource; and serving the particular resource to the client.

Abstract: A method on a device in a content delivery (CD) network (CDN) that distributes content on behalf of one or more subscribers. In response to receiving configuration information from a subscriber, the configuration information relating to at least one property of the subscriber, generating subscriber-specific platform configuration information for the at least one property. Storing the subscriber-specific platform configuration information in platform configuration storage. Invalidating prior platform configuration information associated with the particular subscriber. Responsive to a request from a CDN component for platform configuration information associated with the particular subscriber: obtaining the subscriber-specific platform configuration information from the platform configuration storage; and providing the subscriber-specific platform configuration information to the CDN component.

Abstract: A computer-implemented method, in a content delivery (CD) network, wherein said CD network delivers content on behalf of multiple content providers. The method includes, at a client, requesting one or more parts of a randomly generated test object; in response to said requesting, receiving one or more response objects; generating one or more portions of said randomly generated test object, and comparing the one or more response objects received to at least some of the one or more portions of the object generated. Based on said comparing, when said one or more response objects received do not match said at least some of the one or more portions of the object generated, reporting and logging an error.

Abstract: Provided are computer-implemented methods and systems for performing media resource storage and management. The computer-implemented method and system implemented as a request manager is capable of monitoring requests for media resources in a content delivery network. For each monitored request, the request manager determines whether to generate a multifile for the requested media resource. For example, the request manager can first determine whether the media resource is eligible for multifile generation. If eligible, the request manager then determines whether the media resource has reached a popularity threshold. If the media resource has reached the popularity threshold, the request manager initiates generation of the multifile for the requested media resource. Generally, the generated multifile is stored in a storage system associated with the content delivery network.
