In PyroCMS they use BASE_URI, a 'bandwidth-friendly' constant.

Code:

//constants.php (old code??)
if(isset($_SERVER['HTTP_HOST']))
{
        $base_url = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on' ? 'https' : 'http';
        $base_url .= '://'. $_SERVER['HTTP_HOST'];
        $base_url .= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
        
        // Base URI (It's different to base URL!)
        $base_uri = parse_url($base_url, PHP_URL_PATH);
        if(substr($base_uri, 0, 1) != '/') $base_uri = '/'.$base_uri;
        if(substr($base_uri, -1, 1) != '/') $base_uri .= '/';
}

else
{
        $base_url = 'http://localhost/';
        $base_uri = '/';
}

// Define these values to be used later on
define('BASE_URL', $base_url);
define('BASE_URI', $base_uri);
define('APPPATH_URI', BASE_URI.APPPATH);

// We dont need these variables any more
unset($base_uri, $base_url);
define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');
