  • 0

In C# with MVC, i want to write a common utility or class in which if a particular conditoin fails need to redirect to login page.

For ex.: When the user logged in to the website, userid will be added to session. To Access the “ManageUsers” page, the user should be logged in as admin, else i need to redirect to Login page. i need to check this condition in some of the other similar pages also. i dont want to check either the user is admin or normal user while login. i need to check this in common class.

Any suggesstions?

    Actually I think this is not particularly good behavior for an application. I think you ought to disable (or hide) any actions that a user is not able to perform. In the case where the user hand-enters a URL, or uses a bookmark from when they had the privilege, show an error message rather than redirecting to the login page.

    Imagine you’re a user who is logged into your application. You click on a user interface element and it looks like you’ve been logged out. You have no way of knowing that you weren’t supposed to use it. Disabling/hiding the element prevents this scenario from occurring for most users. Redirecting to an error gives valuable feedback to the user as to why the action they took did not result in what they expected.

    I use a custom attribute derived from AuthorizeAttribute to achieve this effect. If a user isn’t logged in, it redirects to the login page. If they are logged in, but not sufficiently privileged, it displays a suitable error view.
