I am trying to connect to carrier 411 webservice to pull some data but keep getting the below error everytime I call.  If i use the same soap request in SOAP UI tool its giving me soap response.  Could anyone please shed some light into it.

11:54:28.084 (84661000)|CALLOUT_REQUEST|[56]|System.HttpRequest[Endpoint=http://webservices.carrier411.com/wsLogin.cfc, Method=POST]
11:54:28.418 (418009000)|CALLOUT_RESPONSE|[56]|System.HttpResponse[Status=Moved Temporarily, StatusCode=302]

Below is the soap request

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <login xmlns="http://webservices.carrier411.com">
      <param1>user</param1>
      <param2>password</param2>
    </login>
  </soap:Body>
</soap:Envelope>

this is how i am calling the service,,,

 public static string getResponse(String request,String URL)
  {
    try{
      Http h = new Http();
      HttpRequest req = new HttpRequest();
       req.setHeader('Content-Type','text/xml;charset=utf-8');
      req.setMethod('POST');
      req.setEndpoint(URL);
      req.setBody(request);
      req.setTimeout(2000);
      System.Debug('HTTP Request is ' + req);
      HttpResponse res = h.send(req);
      
      System.Debug('HTTP Resonse is ' + res);
      return res.getBody();
    }
    catch(Exception ex) {
        throw ex;
        }
  }
 

This is the webservice  I am trying to call...I am not sure whether  i am missing anything in the header part....
