Classification: CPC G  H | IPC H

Claim 14:
15. An apparatus for preventing access to undesired content, the apparatus comprising:
a wireless data communication interface of a first wireless mesh node that receives a request to access content, the request identifying a content source device;
a memory;
a first cache memory; and
a processor that executes instructions stored in the memory to:
receive the request to access the content at the first wireless mesh node;
determine that information associated with the request does not have a match in contents stored in the first cache memory of the first wireless mesh node, wherein matching content was previously removed from the first cache memory based on an expiration of a first time-to-live time associated with the first cache memory, and wherein the first time-to-live time is based on a number of hops from a mesh portal;
transmit the request to a second wireless mesh node;
determine that the information associated with the request matches a result stored in a second cache memory of the second wireless mesh node, wherein the result remains in the second cache memory longer than in the first cache memory based on the second wireless mesh node being a fewer number of hops from the mesh portal than the first wireless mesh node; and
reject the request based on the matching result stored in the second cache memory.
