Session and subdomain issue

[eluser]CodeMagician[/eluser]
My personal solution was to force the site to run without the "www". That way I knew it would work all the time. Eliminating the need for extensive testing.

I added this code to the top of my /config/config.php file. From line 2, place under BASEPATH security check that's found in line 1.

Code:

/* Remove www */
if(strpos($_SERVER['HTTP_HOST'],'www.')!==false) {
    $url = 'http://mydomain.com.au'.$_SERVER['REQUEST_URI'];
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: '.$url);
    exit();
}
