missing :bin

Return TRUE if the entire resource or the specific requested representation is missing; return FALSE otherwise.

The return value is in the spirit of the 404 NOT FOUND status code.

Reference: HTTPbis, RFC2616

The 404 (Not Found) status code indicates that the origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
