Note that this does not actually prevent the page from being viewed only by admins - ?action=raw, ?action=render, and turning off JS will all allow anyone to view the page content without being barred by the script. It is not possible to prevent people from viewing particular pages on your wiki (and in fact it is a ToU violation to try).
