Description:
------------
This seems to be the same error as bug #42637, but I got it on Windows Server 2003 Standard and PHP version 5.2.5.

I received the following error when trying to execute a soap client function (invokeService):

Fatal error: SOAP Fault: (faultcode: HTTP, faultstring: Unknown protocol. Only http and https are allowed.) in C:\randall\grid.php on line 36


The following functions work fine:
var_dump($client->__getFunctions());
var_dump($client->__getTypes());


Reproduce code:
---------------
try {
	$wsdl   = 'http://KM2BPM1/ApplicationServiceGateway.wsdl';
	$client = new SoapClient($wsdl); 
	$params = array();
	$params['commandLine'] = 'GET.PHONE.EXTENSION.FOR.USER USER=rbrodka';
	$params['options']     = '';
	echo $client->invokeService($params);
} catch (SoapFault $fault) {
   trigger_error("SOAP Fault: (faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring})", E_USER_ERROR);
}

Expected result:
----------------
I expected the code to execute without triggering an error.
