Employing proxy rule identifiers to ensure the integrity of content delivered over an HTTP-over-ICN system. An exemplary method is performed by a client-side network attachment point (cNAP) on an information-centric network (ICN). The cNAP receives an HTTP request that includes a resource identifier and at least one header field. The cNAP generates a proxy rule identifier (PRID) based on the header field(s) and a content identifier (CID) based on the resource identifier. The PRID may be generated by applying a hash function to a string that includes header field data. The cNAP sends an outgoing ICN message that includes the CID and the PRID. In response, the cNAP receives an incoming ICN message that includes an HTTP response, a PRID, and a CID. The cNAP and directs the HTTP response to the appropriate client(s) based on the PRID and CID.
