408 Request Timeout
The HTTP408 Request Timeoutclient error response status code indicates that the server would like to shut down this unused connection.A408 is sent on an idle connection by some servers,even without any previous request by the client.
A server should send theConnection: close header field in the response, since408 implies that the server has decided to close the connection rather than continue waiting.
This response is used much more since some browsers, like Chrome and Firefox, use HTTP pre-connection mechanisms to speed up surfing.
Note:Some servers will shut down a connection without sending this message.
