I suppose the semantics are "due to some reasons the server has chosen to close the connection and return no response to the user"; thus the body in 444 response must be empty.  444 responses must not be stored by the caches, and receiving one should not prevent the user from retrying opening the connection once more.  444 responses should not be generated by intermediaries; they can only be given by the origin servers.

This is returned when a server or an intermediary encounters the situation when due to the limitation of the bandwidth it is unable to process client's request or server's response, respectively.  No caching is allowed as well; "Retry-After" may be present.  I think we can standardize this status code as well.

Interesting enough to include in draft-nottingham-http-new-status?

(Yes, I am reviewing that I-D so that I can create the proto writeup.)
