Gets the contents of the optional response code of the response.
The string containing the inner contents of the optional response (the part of the status response enclosed in square brackets), or a null reference (Nothing in Visual Basic) if the response does not have the optional response code.
For instance, if the optional response code is "[alert]", this property returns "alert". The square brackets themselves are not returned.
