Description:
------------
Hello,

I'm working on an intranet secured with a NTLM authentication.

When a user click on a direct url to a document, and after the NTLM authentication, the document is sent to the client using an http\Env\Response object (php_http.dll v2.0.4).

I set the ResponseCode to 200, but the client receives a 401 code.

When I use the PHP header() function and do 'manually' what http\Env\Response should do, the client receive a HTTP/1.1 200 code.

I checked the HTTP request&response, they are exactly the same. But in the response HTTP status line differs between http\Env\Response and header() method.

Thanks.

Test script:
---------------
<?php
// NTLM authentication
...

// Method 1 : http\Env\Response
$res = new http\Env\Response;
$res->setResponseCode(200);
$res->setCacheControl('private, must-revalidate, max-age=0');
$res->setContentType($mimeType);
$res->setContentDisposition(['attachment' => ['filename' => $filename]]);
$res->setBody(new http\Message\Body(fopen($filename, 'r')));
$res->send();
exit;
...

// Method 2 : header()
header("HTTP/1.1 200 Ok");
header("Cache-Control: private, must-revalidate, max-age=0");
header("Content-type: $mime");
header("Accept-Ranges: bytes");
header("Content-Disposition: attachment; filename=\"$filename\"");
readfile($filename);
exit;
...

?>
