I've used SaltedHashLoginGenerator to protect a few actions within a
controller and all works well.
The only issue is, I need to pass a param that is known before being
redirected to /user/login to the /user/login page and then passed back
to the redirection page after successful login.
A user visits http://whatever.com/home/index?foo=bar
User then clicks a link (/home/content?foo=bar) that is protected with
When being redirected to /user/login, it should pass @params['foo']
and add it to the form submission as a hidden field.
When a user clicks login,
The page they are redirected to should also konw about @params['foo'].
Any help would be greately appreciated.
