title: How to use SOAP::RPC::Driver with basic http authentication with SOAP4r
body: <p>I am generating the stubs in runtime with <code>driver=SOAP::RPC::Driver.new wsdl_path</code>. How should I initialize/configure the driver in order to use http basic authentication? I have tried <code>driver.options["protocol.http.basic_auth"] = [endpoint_url,'username','password']]</code>, though, it fails... </p>
  
  <p>Does anyone know how to do this?</p>
