a hyperlink by selecting a highlighted item displayed in a Web page. HTTP is a

Switching a page presented to a user from a user-selected page to another
HTML page can be desirable. Although such a switch can be implemented by
prompting the user to enter a different HTML page, the appellants assert, "it is more
desirable for this process to occur programmatically." (Id. at 4.) Programmatic
switching allows logic running in a Web server to determine that the HTML page being
viewed in a Web browser should change. "The logic decides which page to go to, and
causes the browser to show the new page without user intervention. The user typically
invokes programmatic switching by selecting a browser-displayed element, for example,
by clicking a button." (Id.)
Accordingly, upon receipt of control information from a client computer, the
appellants' application server executes a script to generate a map that relates HTML
files with commands to show pages related to the HTML files. When a control event is
received from the client computer, the mapping provides a basis for commanding the
client computer's browser to switch to a second HTML page. (Id. at 21.)
