COOKIE SHARING PROGRAM, WEB SERVER WITH COOKIE SHARING FUNCTION, COOKIE SHARING SYSTEM AND COOKIE SHARING METHOD

摘要

PROBLEM TO BE SOLVED: To identify the same user by applying a cookie value common to a user who performs access from a Web server with a different domain, even when a terminal which only accepts a first-party cookie as default such as a smartphone is used.;SOLUTION: When embedding a link to a Web page of a domain B into a Web page of a domain A, a parameter in which a cookie value assigned to identify a user in the Web server of the domain A is set is added to a URL of a link destination. It becomes possible to share the cookie value between the domain A and the domain B and identify the same user by issuing a cookie which adopts the cookie value included in the parameter added to the URL as the cookie value to identify the accessing user if the parameter is added to the URL and the domain A of a link source is a sharing object of the cookie value when accessing the domain B of the link destination.;COPYRIGHT: (C)2013,JPO&INPIT
