Abstract
A device that implements a method for performing integrated caching in a data communication network. The device is configured to receive a packet from a client over the data communication network, wherein the packet includes a request for an object. At the operating system/kernel level of the device, one or more of decryption processing of the packet, authentication and/or authorization of the client, and decompression of the request occurs prior to and integrated with caching operations. The caching operations include determining if the object resides within a cache, serving the request from the cache in response to a determination that the object is stored within the cache, and sending the request to a server in response to a determination that the object is not stored within the cache.
