Redirect to login with redirect_to= original link

Thanks for the plugin.
How can I set the Redirect URL so that it takes the user to the login page and after logging in it redirects them back to the link they initially tried going to?
Basically like the regular wordpress does with
/wp-login.php?redirect_to=xxxxxxxx

Thanks
