ABSTRACT:
An intranet server, memory medium and process for handling requests for resources from a downstream intranet server or a user. The intranet server is configured by a data shadowing program to locally store resources that have a high usage frequency. If a resource has not been requested for a predetermined time out period, it is deleted from local memory. Resources stored in local memory are served in response to requests for them, thus avoiding the service of such resources over the internet each time they are requested. An inquiry procedure handles status requests for new versions in either an active or a passive mode. In the active mode, the intranet server that directly interfaces with the internet periodically checks the status and receives updated versions of resources stored in its local memory. The resources stored in local memory are then served upon request from a user. In the passive mode, status inquiries are sent upstream through the intranet system then via the internet to the web server that serves the resource being requested. The web server returns a revised version only if there is one.
