Abstract

When download operations get started in unison in conformity to RSS metafile delivery time-and-date information, the traffic is temporarily concentrated to a server, resulting in the risk of a system failure or else. In addition, it is inevitable to periodically check whether an RSS file on Web server is updated or not; so, users must delete update-unnecessary RSS files from those objects to be monitored. In view of this, the periodical update check timing of download control information is dispersed, thereby scattering download requests to the server. The download control information is provided with the information indicating whether such download control information is put under update management and/or expire time-and-date information in case the update management is to be done, whereby an information processing apparatus performs, based on the information, erase processing of the download control information when the download processing is completed.
