I am getting this error sporadically too. What I think may be happening is that the webserver HTTP keep-alive time (5 seconds) is at just the right time that the software is somewhat likely to send a subsequent request just before the 5 seconds is up. Then, the server closes the connection as it is on the way and an error occurs. If this is the case, would I be safe to retry that request?
However, the name "NoHttpResponseException" seems to imply that the server may have received the request, but the response cannot be read. That would imply that I would NOT be safe to automatically re-send non-idempotent requests. Is this true? Or can I safely resend all requests? On a side note, is this a common thing that browsers handle all the time?
