     8  `CF_REDIRECT` is the same as `CF_TEMP_REDIRECT` but generates a
     9  http 301 redirect (permanent redirect) instead of a temporary
    10  redirect.
    11  
    12  These redirects are cached by browsers forever, usually ignoring
    13  any TTLs or other cache invalidation techniques.   It should be
    14  used with great care.  We suggest using a `CF_TEMP_REDIRECT`
    15  initially, then changing to a `CF_REDIRECT` only after sufficient
    16  time has elapsed to prove this is what you really want.
