Abstract:
A method, in a data processing system, for redirecting a resource access request for a requested resource, comprising:monitoring a network for resource access requests from a user requesting access to a resource, wherein each resource access request includes a requested resource identifier for said requested resource; determining a current resource identifier for addressing said requested resource by searching a directory for the current resource identifier using the requested resource identifier; and redirecting said resource access request over the network to said requested resource using said current resource identifier responsive to a determination that said requested resource identifier is different from said current resource identifier, by using said current resource identifier instead of said requested resource identifier in the redirected resource access request redirected to said requested resource, wherein resource identifiers are selectively modified in the monitored resource access requests to allow users of the network to request access to network resources using both current and outdated resource identifiers and such access using both current and outdated resource identifiers is transparent to the requested resource, wherein searching the directory includes: searching for the requested resource identifier in a plurality of fields used for storing current resource identifiers; and if the requested resource identifier is not in any of the plurality of fields used for storing current resource identifiers, searching for the requested resource identifier in a plurality of fields used for storing previous resource identifiers, wherein for each resource a plurality of the fields for storing previous resource identifiers are associated with a field for storing a current resource identifier for the resource.
