Abstract:
1. A method of addressing a name space mismatch between content servers and content caching systems, comprising steps of: caching one or more content elements in a content caching system, wherein the cached elements are identified by the content caching system using a uniform resource locator format; automatically learning mappings between a directory structure format and the uniform resource locator format, responsive to receiving the content elements for caching, wherein the received content elements are identifiable to the content caching system using the uniform resource locator format but also have associated therewith identifiers in the directory structure format, the mapping for each received content element storing its identifier in the uniform resource locator format and its associated identifier in the directory structure format; and using the mappings when updating one or more selected cached content elements, responsive to receiving notifications of changed content elements that identify the changed content elements using the directory structure format, by requesting, by the content caching system, updated versions of the selected cached content elements from a content server, wherein each request identifies one of the selected cached content elements using the identifier, in the uniform resource locator format, from the mapping that stores the identifier, in the directory structure format, from the received notification for that content element.
