$http_response_header differs depending on OS

[thuriel]

Hi there,

I hope somebody can help me: I'm making a HTTP request to a source
where I get redirected. Let's assume this page is
"https://www.example.com " and it redirects me to
"https://www.example.com/redirect.html". My request looks like this:

$html = file_get_conten ts('https://www.example.com ');

Now, when I print out $http_response_ headers I get different output on
MacOS/Linux and Windows:

MacOS/Linux:

HTTP/1.1 302 Found
Connection: close
Date: Mon, 26 Feb 2007 15:28:46 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Location: /redirect.html
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 266
HTTP/1.1 200 OK
Connection: close

X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 7830

Windows:

HTTP/1.1 200 OK
Connection: close
Date: Mon, 26 Feb 2007 15:28:46 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 7830

So on Windows I only get the header of the last page I was redirected
to. But I need all the headers on Windows.

Does anybody know which setting is responsible for that? In both cases
(MacOS 10.4 and Windows XP SP2) I am using the latest XAMPP.
