Abstract
The invention relates to an apparatus for responding to data requests made by a client. The apparatus includes an input receiving a first data request that includes a sequence of nodes corresponding to a sequence of servers. The apparatus also includes decision logic determining whether the data specified in the data request is available on a selected server, and if the data is not available determining a next node from the sequence of nodes. The apparatus also includes a mapper mapping a server to the next node, and an output requesting the data by transmitting a second data request to the server mapped to the next node.
