Redirecting to referer

Question

In AngularJS, I have a login controller that is redirected to by every single page in the app if the user arrives at the page and is not logged in. After the login sequence, I would like to redirect the user back to the page that they came from. What's the best way to do this? Save the old location in the $rootScope? Redirect to '/login?returnto=' + $location.path()? Is there a built in function?

Answer 1

You can use $rootScope or define a service to save the old location. Here is a SO post that contrasts the two approaches. I personally don't like adding returnto= to the URL.
