Answer 1

You need to create a session variable on the Login method. The session will be created by Session["Userid"]=Userid;. Then you need to create custom attribute to check session timeout. Steps you need to follow are:

• Create a session variable in login() (Post method)
• Create a class file in your MVC project.

• Copy and paste below code in that file.

  public class SessionTimeOutAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) {

      Controller controller = filterContext.Controller as Controller;
  
      HttpContext httpContext = HttpContext.Current;            
      var rd = httpContext.Request.RequestContext.RouteData;
      string currentAction = rd.GetRequiredString("action");
      string currentController = rd.GetRequiredString("controller");
  
      if (HttpContext.Current.Session["UserId"] == null)
      {
          filterContext.Result = new RedirectResult("~/Account/Login?ReturnUrl=" + currentController + "/" + currentAction);
          return;
      }
      base.OnActionExecuting(filterContext);
  }
  

  }

• add [SessionTimeOut] attribute on each controller.

  [SessionTimeOut]

  public class ControllerName : Controller {

You should add Statup.cs file.
1. Add Statup Class your project from new item lists.
2. Add following line in ConfigureService.

public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc(options => options.EnableEndpointRouting = 
                     false).SetCompatibilityVersion(CompatibilityVersion.Version_3_0);

        services.AddAuthorization();

        services.Configure<ForwardedHeadersOptions>(options =>
        {
            options.ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto;
            // we do this because we trust the network
            options.KnownNetworks.Clear();
            options.KnownProxies.Clear();
        });

        services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
                .AddCookie(x =>
                {
                    x.Cookie.Name = "WriteSomeThings";
                    x.Cookie.SecurePolicy = CookieSecurePolicy.Always;
                    x.Cookie.SameSite = SameSiteMode.Strict;
                    x.Cookie.HttpOnly = true;
                    x.Cookie.IsEssential = true;
                    x.SlidingExpiration = true;
                    x.ExpireTimeSpan = TimeSpan.FromHours(8);//For Auto Logout 
                    x.LoginPath = "/User/LogOn";
                    x.LogoutPath = "/User/LogOff";
                    x.AccessDeniedPath = "/Home/AccessDenied";

                });

    }

x.ExpireTimeSpan = TimeSpan.FromHours(8) => This line allow us to logout automatically after 8 hours.
