The expires header is appropriate. Requests for these methods must go all the way through to the origin server, and cannot be served from a cache themselves. The results can be identified with the Location header in such a way that a subsequent GET or HEAD can retrieve *its* results from the cached resource left in the cache by the POST, PUT, etc. --Shel Kaphan
