Showing popup message for session timeout in MVC

To show a popup message when the session expires and redirect to the login page when the user clicks on the OK button, you can modify your SessionTimeoutAttribute class to check for the session expiration and show the popup using JavaScript.

Here's an example of how you could do this:

public class SessionTimeoutAttribute : ActionFilterAttribute
{
  public override void OnActionExecuting(ActionExecutingContext filterContext)
  {
    HttpContext ctx = HttpContext.Current;
    // Check if session is supported
    if (ctx.Session != null)
    {
      // Check if a new session id was generated
      if (ctx.Session.IsNewSession)
      {
        // Check if the cookie value is the same as the session id
        string sessionCookie = ctx.Request.Headers["Cookie"];
        if ((null != sessionCookie) && (sessionCookie.IndexOf("ASP.NET_SessionId") >= 0))
        {
          if (ctx.Response.IsRequestBeingRedirected == false)
          {
            ctx.Response.Clear();
            ctx.Response.Write("");
            ctx.Response.End();
          }
        }
      }
    }
  }
}

This will show an alert message with the specified message and redirect to the login page when the OK button is clicked.

Hi,

You need to have a code that checks loggedin user or session in one of your controller. The methods that check session should be out of SessionTimeoutAttribute. Check below code for example

    

        

            

                ×
                
Session Expired
            
            

                
Your session is expired
            
            

                Close
            
        
      
    

    var isTimout = false;

    function pingServer() {
        console.log("Ping server");
        if (!isTimout) {
            $.ajax({
                url: '/Home/IsSessionAlive',
                dataType: "json",
                async: false,
                type: "POST",
                success: function (data) {
                    debugger;
                    if (data.isAlive === false) {
                        isTimout = true;
                        $('#myModal').modal('show');
                    }
                }
            });
        }
    }
    setInterval('pingServer()', 10000);

        [HttpPost]
        [AllowAnonymous]
        public JsonResult IsSessionAlive()
        {
            return Json(new
            {
                isAlive = Request.IsAuthenticated
            }, JsonRequestBehavior.AllowGet);
        }
