About
The HTTP 412 Precondition Failed client error response status code
indicates that access to the target resource was denied; this happens
with conditional requests on methods other than GET or HEAD when the
condition defined by the If-Unmodified-Since or If-Match header is not
fulfilled; in that case, the request (usually an upload or a
modification of a resource) cannot be made and this error response is
sent back1.
