It seems from your question you're ignoring the ?n so it's simply:

index.php:

<?php

header("Location: http://www.othersite.com");

?>

try

if (count($_GET))
    {
    header('Location:http://www.myothersite');
    }

You could do the following:

<?php

if(isset($_GET['1'])) {
  header('location: http://othersite.com');
} elseif(isset($_GET['2']) {
  header('location: http://othersite.com/otherpage');
}
//and so on

Later edit:

<?php

    foreach($_GET as $key => $value) {
        if(is_int($key)) {
            header('location: http://othersite.com');
            exit;
        }
    }
