First Claim
Patent Images
1. A system comprising:
- memory for maintaining entries in tracking information, the entries identifying requested resources; and
at least one hardware processor corresponding to a cache management component at a first point of presence (POP) of a content delivery service provider operative to host or process content on behalf of an origin source, the at least one hardware processor executing instructions to;
associate resources obtained from the origin source with entries in the tracking information;
determine one or more entries in the tracking information are invalid prior to termination of expiration criteria associated with one or more resources corresponding to the one or more entries, wherein the determination is based on an invalid tracking information notification received from another cache management component at a second POP of the content delivery service provider; and
update the one or more resources corresponding to the one or more determined invalid entries in the tracking information.

Abstract
A system, method, and computer readable medium for managing resources maintained in resource cache components are provided. A network storage provider storing one or more resources on behalf of a content provider obtains client computing device requests for content. The network storage provider provides resources that are received and maintained on resource cache components. The network storage provider either processes requests or provides notifications to the resource cache components to facilitate the management of resources that need to be updated or are otherwise treated as invalid.

9. A computer-implemented method comprising:
as implemented by one or more computing devices configured with specific executable instructions, the one or more computing devices corresponding to a cache management component at a first point of presence (POP) of a content delivery network (CDN) service provider that hosts or processes content on behalf of an origin source, and the one or more computing devices include a hardware computing device comprising a processor, associating requested resources obtained from the origin source with entries in tracking information, the entries identifying the requested resources; determining one or more entries in the tracking information are invalid prior to termination of expiration criteria associated with one or more resources corresponding to the one or more entries, wherein the determination is based on an invalid tracking information notification received from another cache management component at a second POP of the CDN service provider; and updating, at the CDN service provider, the one or more resources corresponding to the one or more determined invalid entries in the tracking information. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
