Overview

The NOOP command does not cause the server to perform any action beyond acknowledging the receipt of the command. This command can be issued to the server to prevent the client from being automatically disconnected from being idle. It can also prevent modern routers/firewalls from closing a connection that it perceives as being idle as well.

In addition, it is also a browser command so that the session would stay active. In some cases, it usually displays because of customer environment issue.
