Comment #1 on issue 1668 by vladimir.ralev: API to cancel and terminate the transaction when no final response has been received

For now the CSP issue is about the NPE. So we must address it first. Otherwise the logic seems good. The problem with NPE is that the proxy timer is not stopped because the session is not invalidated when the timeout occurs.
