PROBLEM TO BE SOLVED: To enhance utilization efficiency of a cache by combining a cache technique and a recommendation technique.SOLUTION: A content presentation device receives packets, and determines whether the packets are transmitted from a desired site or from others. When the packets are transmitted from the desired site, the device determines whether a content of a content ID is already stored in a cache. If it is not stored in the cache, the device determines a replacement content by referring to the cache on the basis of character strings in the packets, replaces a link destination of the content, and transmits the packets to an original communication path. If the replacement content is not determined, on the basis of words acquired by referring to preference storage means, the device acquires a link destination of a corresponding content from the cache. |
