   A server MAY only allow HDR commands for a limited set of headers and
   metadata items (such as those present in the overview database).  If
   so, it MUST respond with a 503 response to attempts to request other
   headers, rather than returning erroneous results such as a successful
   empty response.

In section 10.6.1.2.
