ajax - With ASP.NET MVC redirect to login page when session expires

Question

I am using ASP.NET MVC. I want to redirect to login page when session expires. How can I achieve this? If I am doing an AJAX call to a method in controller then if my session expires in that situation also I want to redirect to login page.

Answer 1

you could do this by 3 ways:

1. Create a filter to your actions and apply it programming a code in OnActionExecuting (before the action been executed), http://www.asp.net/mvc/tutorials/understanding-action-filters-cs

2. Create a base class (inheriting from Controller class) and make your controllers inherits from this one. In this class you could overwrite a method called OnActionExecuting, like the filter.

3. Don't use Session for Authentication, you can use Forms authentication and keep it simple to use, look this: http://weblogs.asp.net/fredriknormen/archive/2008/02/07/asp-net-mvc-framework-using-forms-authentication.aspx

In my opinion, the solution 3 is better than other. I hope it works for you!
