Description:
------------
For the web site http://istt2012.comvt.org (which has one redirection), 
getResponseCode returns 302, while getResponseInfo() returns a response_code field 
of 200. In both cases, the documentation indicates that the final (last) response 
code, presumably 200, should be returned.

Test script:
---------------
$url = "http://istt2012.comvt.org";
   $r = new HttpRequest($url, HttpRequest::METH_GET);
    $r->setOptions(array(
       'redirect' => 10,
       'timeout' => 10,
       'dns_cache_timeout' => 5));
    try {
      $r->send();
      $rc = $r->getResponseCode();
      $ri = $r->getResponseInfo();
    }

Expected result:
----------------
$rc = 200;
$ri['response_code'] = 200
