ABSTRACT:
A method in which a data access request by a user to access data of a destination server, such as the data that needs to be updated when a login and/or password is changed, is provided consistently. The destination servers are redundant, and instead of directing the access request directly to one of the redundant destination servers, an intermediate level of servers is provided that selects one of the destination servers to serve the data access request. This selection is made so that the data access request from a particular source may be directed to the same destination server. The data access request includes data that is unique to the source and/or to the user, and the selection is made in dependence on the result of a transformation, such as a hash function, performed on the unique data. Since the redundant destination servers may each identically serve the data access request, the data access request can be routed to any destination server without any change in the processing of the request.
