 * The ICAP Initiator is an ICAP vectoring point that initates ICAP
 * transactions. This interface exists to allow ICAP transactions to
 * signal their initiators that they have the answer from the ICAP server
 * or that the ICAP query has aborted and there will be no answer. It
 * is also handy for implementing common initiator actions such as starting
 * or aborting an ICAP transaction.
