I am aware that there is already some threads within the Q&A about this although nothing specific to my needs. I am trying to pass a SOAP header username and password yet can't find a way to achieve this. I have imported and am using the Flex SDK within Flash which supports WS but cant seem to implement the headers correctly. I am now coming to a close to the end my first day scouring the internet to no avail. Any help would be gratefully appreciated.
