send HTTP_RANGE to a HTTP request

[Chameleon]

I want a php script for this:

1. make a http request to a web page and send to that page HTTP_RANGE.
2. get headers from that page for testing.

-----------------------------
<?php
$url = 'http://127.0.0.1/';
$fp = fopen($url, 'r');
$meta_data = stream_get_meta_data($fp);
foreach ($meta_data['wrapper_data'] as $v)
echo "$v\n"
?>
-----------------------------
the only thing I dont know, is how to send HTTP_RANGE to server
