Patent ID: 8468222

Claim:
A method for caching content in a carrier network that provides data access, said method comprising: caching a plurality of content to a caching server, wherein the plurality of content comprises content from a particular content provider; issuing, to a first Domain Name System (DNS) server, a DNS update based on the plurality of content that is cached by the caching server, wherein the first DNS server is operated by the carrier network to initiate resolution of a set of DNS requests originating from within the carrier network, and wherein issuing the DNS update reconfigures the first DNS server by modifying a DNS entry at the first DNS server to resolve a request that identifies at least one of (i) a hostname and (ii) a domain for the particular content provider to an address of the caching server, wherein the address of the caching server is different than an address that is resolved for the request by a second DNS server that is authoritative for the hostname and domain of the particular content provider; resolving the request that identifies at least one of (i) a hostname and (ii) a domain for the particular content provider at the first DNS server based on the modified DNS entry without reference to the second DNS server; and passing cached content from the caching server in response to the request.
