server MUST NOT perform the requested method when If-None-Match matches ETag and IMS matches LMT


This test clause tests the following 3 requirement(s).

  1. "If any of the entity tags match the entity tag of the entity that would have been returned in the response to a similar GET request (without the If-None-Match header) on that resource, or if "*" is given and any current entity exists for that resource, then the server MUST NOT perform the requested method, unless required to do so because the resource's modification date fails to match that supplied in an If-Modified-Since header field in the request" (rfc2616)
  2. "For all other request methods, the server MUST respond with a status of 412 (Precondition Failed)" (rfc2616)
  3. "The meaning of "If-None-Match: *" is that the method MUST NOT be performed if the representation selected by the origin server (or by a cache, possibly using the Vary mechanism, see section 14.44) exists, and SHOULD be performed if the representation does not exist" (rfc2616)
