Subject: How can I populate header values in SOAP document?

Hi all,

Got a question about the Ruby SOAP library.  I've generated a proxy
using the SOAP::WSDLDriverFactory as follows:

ws =
SOAP::WSDLDriverFactory.new('http://foo.com/foo.wsdl').create_rpc_driver

I can see that this generates methods for each defined operation, and I
use them thusly:

ws.WSGetResults(:maxRecords => 1, ...)

The method and parameters are translated to the appropriate XML in the
SOAP message body.  However, some operations require a 'User' and
'Password' to be in the message _header_.  I've looked through the
documentation and mailing lists with no luck.  How can one achieve this?

My code is listed below.

Thanks!

---- soaptest.rb ----
require 'soap/wsdlDriver'
require 'date'

ws =
SOAP::WSDLDriverFactory.new('http://foo.com/foo.wsdl').create_rpc_driver
ws.generate_explicit_type = true
r = ws.WSHeartbeat({}) # Works because it doesn't require authentication
r = g.WSGetXmlResults(:recordId => 123, :recordLimit => 200) # Doesn't
work

---- Example SOAP request, according to vendor ----
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Header>
    <!-- I don't know how to populate the header -->
    <WSAuthHeader xmlns="http://foo.com/WSFooSvc">
      <User>string</User>
      <Password>string</Password>
    </WSAuthHeader>
  </soap:Header>
  <soap:Body>
    <WSGetXmlResults xmlns="http://foo.com/WSFooSvc">
      <recordId>int</recordId>
      <recordLimit>int</recordLimit>
    </WSGetXmlResults>
  </soap:Body>
</soap:Envelope>
