The present invention adds new value to the Web, such as to improve accessibility, while maintaining changes to existing web sites to a minimum. An example system includes a first Web server and at least one other Web server, wherein a Web page can be displayed on a Web browser in a client device connected with the first Web server and the other Web server via a network, wherein the first Web server registers URLs of files providing added value for each of the first Web server and the other Web server that are defined as a set of Web servers to be provided with the same added value, and wherein the first Web server and the other Web server display an existing Web page in the Web browser, and provide the added value to the Web page by manipulating a DOM from another frame or another window.
