<P>
This interface represents the RAck header, as defined by <a href = "http://www.ietf.org/rfc/rfc3262.txt">RFC3262</a>, this header is not part of RFC3261. <p> The PRACK messages contain an RAck header field, which indicates the sequence number of the provisional response that is being acknowledged (each provisional response is given a sequence number, carried in the RSeq header field in the Provisional response). The acknowledgements are not cumulative, and the specifications recommend a single outstanding provisional response at a time, for purposes of congestion control. <p> The RAck header contains two numbers and a method tag. The first number is the sequence number from the RSeqHeader in the provisional response that is being acknowledged. The next number is the sequence number that is copied from the CSeqHeader along with the method tag, from the response that is being acknowledged. <p> For Example:<br> <code>RAck: 776656 1 INVITE</code> <p> A server must ignore Headers that it does not understand. A proxy must not remove or modify Headers that it does not understand.
