The invention discloses an information processing method and a corresponding device, which are used for solving the problem of overlong total time taken for service processing as a node returns a response result based on a retransmission service request in the prior art. The information processing method comprises the steps of, by a storage node, receiving a first request which is sent by a server, wherein the first request comprises a first request identifier which is used for representing content requested by the first request; obtaining the first request identifier from the first request and judging whether the first request identifier is stored in a local cache by the storage node, wherein the request identifier contained in the request which is received by the storage node is stored in the local cache of the storage node; if the first request identifier is stored in the local cache of the storage node, regarding a second response result of a second request which contains the first request identifier and is received before the first request as a first response result of the first request by the storage node; and returning the first response result to the server by the storage node.
