A history registration unit (120) registers, in a history file (191), designated location information that specifies a location at which a transition source page is designated, whenever any one link is designated in the transition source page including a plurality of links related to other web pages. For each page area obtained by dividing the transition source page, a probability calculating unit (130) calculates a probability that a link included in a page area is designated, by using the designated location information registered in the history file. A page acquiring unit (140) selects a page area on the basis of the probability for each page area, acquires, from the transition source page, a link included in the selected page area, and acquires a web page related to the acquired link. A cache unit (150) stores the acquired web page in a cache memory (9011). |
