There are several ways to accomplish this task, but the simplest to understand is to use php.
To do this, you need to create the page that will do the forwarding. This can be any page, as long as it ends in ".php". If you are trying to redirect a domain, you'd create "index.php" inside the public_html directory.
Once you decide which page you will use, then create the file and enter the following text:
header("Location: http://whereyouwant.com/to/go.html");
?>
Where http://whereyouwant.com/to/go.html is the location that you want the page to forward to. You can use local values, ie: /page.html, or full urls as in the above example (http://..etc.)
