I discover very simple way to redirect Login Page When session end in MVC. I have already tested it and this works without problems.

In short, I catch session end in _Layout 1 minute before and make redirection.

I try to explain everything step by step.

If we want to session end 30 minute after and redirect to loginPage see this steps:

Change the web config like this (set 31 minute):

 <system.web>
    <sessionState timeout="31"></sessionState>
 </system.web>

Add this JavaScript in _Layout (when session end 1 minute before this code makes redirect, it makes count time after user last action, not first visit on site)

<script>
    //session end 
    var sessionTimeoutWarning = @Session.Timeout- 1;

    var sTimeout = parseInt(sessionTimeoutWarning) * 60 * 1000;
    setTimeout('SessionEnd()', sTimeout);

    function SessionEnd() {
        window.location = "/Account/LogOff";
    }
</script>

Here is my LogOff Action, which makes only LogOff and redirect LoginIn Page

public ActionResult LogOff()
{
    Session["User"] = null; //it's my session variable
    Session.Clear();
    Session.Abandon();
    FormsAuthentication.SignOut(); //you write this when you use FormsAuthentication
    return RedirectToAction("Login", "Account");
}

I hope this is a very useful code for you.

One way is that  In case of Session Expire  in every action you have to check its session and if it is null then redirect to Login page   But this is very hectic method To over come this you need to create your own ActionFilterAttribute which will do this  you just need to add this attribute in every action method   Here is the Class which overrides ActionFilterAttribute   public class SessionExpireFilterAttribute   ActionFilterAttribute               public override void OnActionExecuting ActionExecutingContext filterContext                        HttpContext ctx   HttpContext Current                  check if session is supported             CurrentCustomer objCurrentCustomer   new CurrentCustomer                objCurrentCustomer     CurrentCustomer SessionStore GetSessionValue SessionStore Customer                if  objCurrentCustomer    null                                   check if a new session id was generated                 filterContext Result   new RedirectResult    Users Login                    return                             base OnActionExecuting filterContext                     Then in action just add this attribute like so    SessionExpire  public ActionResult Index          return Index        This will do you work

There is a generic solution   Lets say you have a controller named Admin where you put content for authorized users   Then  you can override the Initialize or OnAuthorization methods of Admin controller and write redirect to login page logic on session timeout in these methods as described   protected override void OnAuthorization System Web Mvc AuthorizationContext filterContext                  lets say you set session value to a positive integer         AdminLoginType   Convert ToInt32 filterContext HttpContext Session  AdminLoginType             if  AdminLoginType    0                        filterContext HttpContext Response Redirect    login                       base OnAuthorization filterContext
