Abstract: A computer implemented method enables user access, over a network, to a resource which can be accfessed from any one of a plurality of sites. The method initially stores a control data structure which includes (i) a plurality of site addresses where copies of the resource reside and (ii) an entry which enables access to a procedure that defines a criteria for selecting one of the plurality of site addresses from which to access a copy of the resource. Next a Web page is displayed, having a region which indicates the resource. The method then responds to a user's selection of the region, by accessing the control data structure and executing the procedure so as to enable access by the user to the resource in accord with the selection criteria, without requiring further input by the user.
