Setting up WOL for custom script

[WorldCraft]

I'm trying to set up a WOL entry for a custom script. However the script is named index.php and in a directory above my forum root.

If I use:

PHP Code:

switch ($filename)
{
    case 'index.php':
        $userinfo['activity'] = 'mypage';
        break;
} 


Won't this apply the WOL for ALL scripts titled index.php??? It's the only method I know how to add a WOL entry. Is there another way?
