Abstract
A content delivery network (CDN) comprises a set of edge servers, and a domain name service (DNS) that is authoritative for content provider domains served by the CDN. The CDN is extended into one or more mobile or wireline networks that cannot or do not otherwise support fully-managed CDN edge servers. In particular, an 'Extender' is deployed in the mobile or wireline network, preferably as a passive web caching proxy that is beyond the edge of the CDN but that serves CDN-provisioned content under the control of the CDN. The Extender may also be used to transparently cache and serve non-CDN content. An information channel is established between the Extender and the CDN to facilitate the Extender functionality.
