PROBLEM TO BE SOLVED: To solve the problem in which when look-ahead processing by many clients are performed simultaneously, load on a server can increase too much.SOLUTION: According to the present invention, a plurality of files to be looked ahead are identified, the identified plurality of files to be looked ahead are downloaded from a server in order, download speed when downloading one of the plurality of files to be looked ahead is calculated, and it is determined whether or not the calculated download speed is threshold or larger. When it is determined that the download speed is threshold or larger, a file to follow among the plurality of files to be looked ahead is downloaded. When it is determined that the download speed is smaller than the threshold, download is performed with a file of a file size or smaller that can be downloaded for a prescribed time at the download speed among the plurality of files to be looked ahead as a next look-ahead object.SELECTED DRAWING: Figure 6 |
