Coldfusion SOAP Web Service Requests issue

Hi there!
I have a ColdFusion 9 server. I need to make a SOAP Web Service request using Coldfusion but it does not work. The way it should work: coldfusion page sends a filtered SOAP service request to a remote (non coldfusion) server and the  returned page needs to be saved to a DB. I tried to follow Ben Nadel samples (http://www.bennadel.com/blog/1809-making-soap-web-service-requests-with-coldfusion-and-cfhttp.htm) but I'm getting a BLANK page in return.

Here is my request page:

<cfsavecontent variable="soapBody">
<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header/>
   <soapenv:Body>
      <sch:GetClient>
         <!--Optional:-->
         <sch:request>
            <sch:RequestHeader>
               <!--Optional:-->
               <sch:ClientVersion>1001</sch:ClientVersion>
               <!--Optional:-->
               <sch:CustomerKey>123456789</sch:CustomerKey>
               <!--Optional:-->
               <sch:Password>MyPassword</sch:Password>
               <!--Optional:-->
               <sch:User>user@MyDomain.com</sch:User>
            </sch:RequestHeader>
            <!--Optional:-->
            <sch:Filter>
               <!--Optional:-->
               <sch:ClientID>456</sch:ClientID>
            </sch:Filter>
         </sch:request>
      </sch:GetClient>
   </soapenv:Body>
</soapenv:Envelope>
</cfsavecontent>
 
<cfhttp url="https://webservice.domain.com/services/soap/2.1/Services.svc?wsdl" method="post" result="httpResponse">

<cfhttpparam type="header" name="SOAPAction" value="https://webservice.domain.com/services/soap/2.1/GetClient"/>
 
<cfhttpparam type="header" name="accept-encoding" value="no-compression"/>
<cfhttpparam type="xml" value="#trim( soapBody )#"/>

</cfhttp>
 

<cfif find( "200", httpResponse.statusCode )>
 
      
      <cfset soapResponse = xmlParse( httpResponse.fileContent ) />
 
      <cfset responseNodes = xmlSearch(
            soapResponse,
            "//*[ local-name() = 'GetClient' ]"
            ) />
 
      <cfoutput>
 
            Code: #responseNodes[ 1 ].Code.xmlText#
            <br />
            Success: #responseNodes[ 1 ].Message.xmlText#
      </cfoutput>
</cfif>

I dont know why it does not work.
Thanks for your help!
