browser issue?

Because clients don't always send the referrer.  No bug here.  PHP will
have it if the client provides it, otherwise it won't.

Description:
------------
$_SERVER['HTTP_REFERER']; doesn't always display

It displays occassionally, but not all the time.

Reproduce code:
---------------
<?php
$send_ip = $_SERVER['REMOTE_ADDR']; 
$send_agent = $_SERVER['HTTP_USER_AGENT'];
$send_refer = $_SERVER['HTTP_REFERER'];
?>

<table border="0">
<tr>
 <td><?php echo $send_ip; ?></td>
</tr>
<tr>
 <td><?php echo $send_agent; ?></td>
</tr>
<tr>
 <td><?php echo $send_refer; ?></td>
</tr>
</table>

Expected result:
----------------
<browser's_IP address>
<referring page>
<browser type>

Actual result:
--------------
<browser's_IP address>

<browser type>
