A data-processing system includes a storage device for running a local web-server residing in the storage device; a host device for connecting to the storage device; and an exchanging mechanism, residing in the host device, for exchanging information autonomously between the local web-server and a remote web-server connected to the host device. Preferably, the local web-server serves a host application, upon a host-application request for information when the local web-server cannot obtain the information, by retrieving the information autonomously from the remote web-server via an LWSA. Preferably, the exchanging mechanism exchanges data packets between the local web-server and the remote web-server. Preferably, the storage device initiates the exchanging of the information upon indication of available bandwidth for network communication. More preferably, the storage device prioritizes the exchanging of the information according to a protocol that takes into account statistics of data usage according to temporal parameters of the data usage.
