Login/out without going to WP Default Login Page/Dashboard but referring page

I have a situation that I have a page that have hidden text in it. Only the subscriber can see it after they login.
In that page, I want to send the user to login, after login, Can I send the user back to the referral page (the page has the hidden page) instead of dashboard?
Another alternative is, a login on the sidebar, once login, go back to the current page instead of dashboard.
Thanks.
