Header does not include client id in AMF Request

When authenticating, a client id is passed back in the response message. However, the next message sent to the server does not have this information (DSId=xxxx and DSValidateEndpoint=true). So when it will fetch a new Flex Client and not be authorized, throwing a access denied exception.

How can I take the clientId out of the response message when authenticating and put it in the header of my requests?

Thanks...
