When connecting to a content server to request a content by an intention of the user, the user terminal 2 transmits a Cookie of the content server, but disables the transmission of the ugID that is in use then. When transmitting an advertisement request signal to an advertisement delivery server on the basis of an advertisement tag received along with the content irrespective of the intention of the user, the user terminal transmits the ugID that is in use then, but disables the transmission of the Cookie of the content server.SELECTED DRAWING: Figure 2 |
