ABSTRACT:
A content delivery network has a content switch that intercepts content requests transmitted toward the origin server. The content switch distinguishes the content request as originating either external to the content delivery network or from within the content delivery network. The content switch forwards external requests to a content router, within the content delivery network and forwards internal requests to the origin server. Devices external to the content delivery network do not access the content carried by the origin server directly and, therefore, the content delivery network does not require the origin server alter its content when storing the content on a content server within the content delivery network. Use of the content switch, therefore, minimizes or eliminates the time, effort, and expense of rewriting content cached from the origin server to the content server within the content delivery network.
