In a particular case the PHP session_start doesn't work

Question

If I type an URL e.g. www.vdh-lelystad.nl the PHP session_start() does work very well. All the SESSION variables are available trhoughout the website visit.<br />
If I type URL vdh-lelystad.nl (without www.) no PHP session_start() will be there. No SESSION variables are available.
(In Chrome or IE if you type a URL without www. they put it automatically in front of the URL).<br />
Please can you tell me what to do about it so that if people type the URL without www. ther won't be any problem. First it cost me a lot to find out what happened, and second it already took me a lot of time to try something, so I could put it in front of the URL myself (e.g. $URL = $_SERVER['SERVER_NAME'];<br />
$URL = explode('.', $_SERVER['SERVER_NAME']);<br />
<br />
<pre><nowiki>
if(strtolower($URL[0]) <> 'www')
$_SERVER['HTTP_HOST'] = "www.vdh-lelystad.nl";
header("Location: " . $_SERVER['HTTP_HOST']);
exit;
}</nowiki></pre>
But that doesnot work cause the second time the URL will be:<br />
vdh-lelystad.nlwww.vdh-lelystad.nl.<br />
You make me happy if you know a way to solve this problem.<br />
Many thanks in advance.
Best regards<br />
