3.2.5.8 Sent Client Request State

If the response received from the server contains a structurally valid response, the TDS client MUST indicate the result of the request to the upper layer and enter the "Logged In" state.

The client has the ability to return data/control to the upper layers while remaining in the "Sent Client Request" state while the complete response has not been received or processed.

If the TDS client supports Cancel Request and the upper layer requests a Cancel Request to be sent to the server, the TDS client sends an Attention message to the server, start the Cancel Timer, and enter the "Sent Attention" state.

If the response received from the server does not contain a structurally valid response, the TDS client MUST close the underlying transport connection, indicate an error to the upper layer, and enter the "Final State" state.
