Abstract
Mechanisms are provided to allow efficient delivery of content through a content delivery network (CDN) without taxing an origin server while maintaining fine grained location based access control. Requests to a CDN are augmented with quantized and non-quantized versions of location information. A CDN can use quantized location information in a URI to identify and return content if content corresponding to the URI is available in cache. If the content is not available in cache, the CDN can contact an origin server to obtain a result for the request using non-quantized location information. The origin server examines the non-quantized location information to determine whether to respond to the client request with content. The origin server examines the area corresponding to the quantized location information to determine whether the content should be cached at the CDN.
