Passing a cookie to a webservice using SOAP

Hi can anyone tell me if it is possible to create a cookie and pass the cookie in a header to a webservice. The cookie will be a sort of parameter for the webservice. Is it something like this: // Define the SAMS cookie and store value in header Header ('setcookie: name=value') ; require_once('nusoap/nusoap.php'); // Define the webservice's WSDL $serviceWSDL = "http://www.site/?WSDL" //Create a SOAP client which references the Web Service $soapclient = new soapclient($serviceWSDL, 'wsdl'); //Invoke the Web service's GetCustmisation function (cookie should supply value) $returnvalue = $soapclientcall->('Function') //Show $returnvalue Echo $returnvalue Any help would be appreciated thanks Steven
