[web2py] How to make address bar to correspond to the _next link redirection? /user/login still shows after login

[Constantine Vasil]

After login, the _next link successfully redirect to my home page 
as I expected.

The address bar shows /user/login#/user/login

When I hit the browser back button it goes back to the login page.

How to make the address bar to change according to the page 
where it was redirected?
