Only coarse request metadata is shown. This demo does not display or persist visitor IP addresses.
Parameter 1 controls the language name displayed, while parameter 2 controls the links. Thus 1 should be a language name NOT followed by "language" (thus, "English" rather than "English language), and 2 should be an ISO 639 code ("eng"). 1 is unnecessary unless there exists no ISO 639 code for the language.
