              auction demo entered an endless loop. ICEpush should not simply accept an empty response, this should be an error condition that causes the connection to be aborted. (It may make sense to allow a fixed number of empty responses.)

              This looping request/response (at a very high rate) sometimes begins when the application is restarted. The bridge should not continually make requests to the server if the response is empty.

              Re-opening issue to be considered fixed as follows: under no condition will ICEpush return an empty response, and after a small number (say 3) empty responses in a row, the client-side bridge will abort the connection.

              Introduced mechanism that detects when consecutive empty responses are received. The number of retries can be set by the org.icepush.emptyResponseRetries context parameter. The default number of retries is 3. Once the retries are consumed the bridge will stop sending blocking requests.
