The present invention relates to a method of dealing with inquiries for data-information within a network. Acting within the network is a cache that includes a number of nodes and in which data-information is found available for a given period of time so as to meet inquiries from different users, subsequent to having fetched the data-information from a server (3). The cache nodes form a hierarchical node tree structure. This tree structure includes a plurality of object nodes (2a1, 2a2, ..., 2a5), a plurality of directory nodes (2b1, 2b2, 2b3), and a root node (2c). The obje ct nodes (2a1, 2a2, ..., 2a5) are positioned furthest out in the tree structure, whereas the root node (2c) constitutes the root of the tree structure, and any intermediate levels between an object node and the root node are comprised of directory nodes (2b1, 2b2, 2b3). All data- information is stored within object nodes (2a1, 2a2, ..., 2a5). Respective directory nodes (2b1, 2b2, 2b3) and the root node (2c) include a directory that covers all data-information stored within object nodes that are located beneath the node in the tree structure, and within which object node respective data-information is stored. When needing to transmit data-information requested by a user (1b) via a first object node (2a3), theobject node (2a2) that has the requested data-information is ordered to send this information to the first object nod e (2a3).
