Redirect after registering with Drupal

Question

Does anyone know how to return to the "last page" after the user is presented with a login screen and you want to create a new account?

Basically the sequence:

• User is trying to get protected content
• Redirected to login page
• If it logs in, it is redirected to the original page
• If he selects "create a new account" and fills it out, he is redirected to the home page

How do we automatically redirect it to the original page (and not to the static page).
