Reading SOAP Headers in web service

I am writing a web service in ColdFusion 8 that will read the following SOAP envelope.  

   <?xml version="1.0" encoding="utf-8"?>
   <soap:Envelope>
    <soap:Header>
     <WSSecurity>
      <Search>1</Search>
      <User>2</User>
      <Account>3</Account>

      <Password>pass</Password>
     </WSSecurity>
    </soap:Header>
    <soap:Body>
     <SessionTransfer>
      <SearchCriteria>Message</SearchCriteria>
     </SessionTransfer>
    </soap:Body>
   </soap:Envelope>

This is the first time I have ever wrote a webservice.  I have consumed them before.  So my problem is I cannot read the SOAP header!!  In the cfc it gets pass the IsSOAPRequest.  So I think the value coming in is correct.  The request is all there except the headers.  I have read about the getSOAPRequestHeader but that appears to be useful for the person consuming this werbservice and not on my end writing the service.  I could be wrong (and probably am)!  Please help!!

Thanks
