Abstract

A content delivery method directs a request by a client for an object to a first server in a content delivery network (CDN), regardless of whether the first server has the requested object. If the first server has the requested object, then it is served to the client from the first server; otherwise, the first server redirects the client request to a second server in the CDN to handle the request. The second server may be a peer server of the first server. The first and second servers may be edge servers in the CDN.
