# Every authorization server response is uncacheable and sends no Referer to
# another site, whether it succeeds, fails, or never reaches its action. The
# pages a GET renders send ours to us alone (same-origin), so a browser keeps
# its Origin on the forms they post back; every other answer sends none.
