title: Return to previous page after login
body: <p>Oi!</p>
  
  <p>I have wanted a returntosamepageafterlogin-feature on my site for a long time. But whats the best way?</p>
  
  <p>I was thinking about saving the url into a session and when he/she logins, i check if the returnto-session if set, if it is, i redirect to that page</p>
  
  <p>Is that safe/good?</p>
