Patent number: 8780708Abstract: A control server 4, receives the number of user terminals U which have transited to the individual Web pages from a monitoring server 3 in Step S41. In Step S42, based on the received number of transitions U of the individual Web pages, application of control is decided by the control server 4. Here, based on the assumption that the number of transitions Uc to a Web page C including a transaction access or hyper link to the end server 2 accurately represents the number of executed transactions, the number of transitions Uc to Web page C is compared with an upper limit value Cmax. When Uc<Cmax, the process proceeds to Step S43 and a control information is sent from the control server 4 to the user terminals 1 to cancel the application of control.Type: GrantFiled: March 30, 2009Date of Patent: July 15, 2014Assignee: KDDI CorporationInventors: Hideyuki Koto, Yasuhiko Hiehata, Satoshi Uemura, Hajime Nakamura
