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.

2. A method, comprising:
-
receiving a resource request from a client, the resource request received at a content delivery network server, the resource request including non-quantized location coordinates; parsing the resource request to identify quantized location coordinates; and when it is determined that the identified quantized location coordinates fail to meet a specified granularity threshold, transmitting a redirect request message to the client requesting quantized location coordinates, the quantized location coordinates having greater granularity than the non-quantized location coordinates. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 17, 18, 19)

15. The method of claim Ii. wherein the origin server indicates to the content delivery network server that the location restricted resource should not be cached if the region defined by the quantized location coordinates falls partially within a non-restricted zone.
-
16. A system comprising:
-
memory configured to store a resource request received from a client, the resource request received at a content delivery network server, the resource request including non-quantized location coordinates; a processor configured to parse the resource request to identify quantized location coordinates; and a network interface configured to transmit a redirect request message to the client requesting quantized location coordinates, when it is determined that the identified quantized location coordinates fail to meet a specified granularity threshold, the quantized location coordinates having greater granularity than the non-quantized location coordinates.

20. One or more non-transitory computer readable media having instructions stored thereon for performing a method, the method comprising:
-
receiving a resource request from a client, the resource request received at a content delivery network server, the resource request including non-quantized location coordinates; parsing the resource request to identify quantized location coordinates; and when it is determined that the identified quantized location coordinates fail to meet a specified granularity threshold, transmitting a redirect request message to the client requesting quantized location coordinates, the quantized location coordinates having greater granularity than the non-quantized location coordinates.
