1. A method for preventing access to undesired content, the method comprising:
receiving a request to access content at a first wireless mesh node, the request identifying a content source device;
determining that information associated with the request does not have a match in contents stored in a 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;
transmitting the request to a second wireless mesh node;
determining 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
rejecting the request based on the matching result stored in the second cache memory.
