如果用户登陆受保护页面，那么如何根据用户角色进行重定向？

Question

I'm using Asp.net Identity.

Currently have 7 types or roles in the system. A user can only have 1 role. How can I set the redirect URL based on the user role if that user lands on a protected page that his role doesn't have privilege to?

For example a Student user of role Student goes to Teacher.aspx . He is not authorized so the default is that he is redirected to the login page. But I would much rather redirect him somewhere else depending on his role because he is already logged in.

User the System.Web.Mvc.AuthorizeAttribute attribute. You can use it like so:

[Authorize(Roles="AuthorizedRoleOne,AuthorizedRoleTwo")]
public ActionResult Index()

By default it will redirect unauthorized users to a login page. If that isn't what you want have a look at this question (you can inherit from the attribute and change the behavior).
