Ticket #371 (closed editorial: incorporated)
If-Modified-Since lacks definition for method != GET

The "If-Modified-Since" header field MAY be used to make a request method conditional by modification date: if the selected representation has not been modified since the time specified in this field, then do not perform the request method; instead, respond as detailed below.
This section doesn't seem to say anything about methods other than GET, yet the text seems to imply that a more general case is also covered below.
