问题 I just learn about ASP.NET MVC. I hava a website with this following scenario: Login -> Main Page (Index) -> Edit Page (Edit) So, In LoginController when user login, it will redirect to main page and edit a record from MainPage . Everytime a new record is created through ASP.NET MVC, the system will send an email to manager. Within email message, there is a hyperlink that will redirect the manager to edit form. But first, he needs to login because the edit form cant be opened unless he login.
