A method for handling content requests received in a CDN using an intermediate server may include maintaining a virtual file server that provides virtualized access to content in multiple POPs throughout the CDN, receiving a content request sent to the CDN, making a local request to the virtual file server for the content, where the specialized virtual file server may determine that the content is stored in a second POP that is remotely located from the first POP, and the specialized virtual file server may retrieve the content from the second POP and provide the content to the intermediate server as though it were stored locally in the first POP. The method may also include receiving the content from the specialized virtual file server, where the specialized virtual file server makes the requested content appear to be a locally-stored file to an operating system of the intermediate server.
