There is a typo in Lymber's comment.
Instead of
$httpRequest_OBJ->setContentType = 'Content-Type: text/xml';
use
$httpRequest_OBJ->setContentType('text/xml');

The HttpRequest class does support redirects, but it's disabled by default. To enable redirect do something like this:
<?php
// Set number of redirects to a reasonable number.
$r->setOptions(array('redirect' => 10));
?>

Example how to use HttpRequest to post data and receive the response:
<?php
//set up variables
$theData = '<?xml version="1.0"?>
<note>
<to>php.net</to>
<from>lymber</from>
<heading>php http request</heading>
<body>i love php!</body>
</note>';
$url = 'http://www.example.com';
$credentials = 'user@example.com:password';
$header_array = array('Expect' => '',
'From' => 'User A');
$ssl_array = array('version' => SSL_VERSION_SSLv3);
$options = array(headers => $header_array,
httpauth => $credentials,
httpauthtype => HTTP_AUTH_BASIC,
protocol => HTTP_VERSION_1_1,
ssl => $ssl_array);
//create the httprequest object
$httpRequest_OBJ = new httpRequest($url, HTTP_METH_POST, $options);
//add the content type
$httpRequest_OBJ->setContentType = 'Content-Type: text/xml';
//add the raw post data
$httpRequest_OBJ->setRawPostData ($theData);
//send the http request
$result = $httpRequest_OBJ->send();
//print out the result
echo "<pre>"; print_r($result); echo "</pre>";

Note that send() does not process redirects, and there doesn't appear to any way to get this to happen automatically. If you need to follow redirects, use something like the following code:
<?php
$request = new HttpRequest($url, HTTP_METH_GET);
do {
$response = $request->send();
if ($response->getResponseCode() != 301 && $response->getResponseCode() != 302) break;
$request->setUrl($response->getHeader("Location"));
} while (1);
?>
