Their server is broken in that it doesn't handle HEAD requests.

    The methods GET and HEAD MUST be supported by all general-purpose
    servers. 
      -- http://www.w3.org/Protocols/rfc2616/rfc2616-sec5.html#sec5.1.1

   The HEAD method is identical to GET except that the server MUST NOT
   return a message-body in the response. The metainformation contained
   in the HTTP headers in response to a HEAD request SHOULD be identical
   to the information sent in response to a GET request.
