Hi Piyush, Please do needful as below in startup.cs page, services.AddSession(options => { options.IdleTimeout = TimeSpan.FromMinutes(30); options.Cookie.IsEssential = true; }); services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme) .AddCookie(options => { options.Cookie.Name = "YourCookieName"; options.Cookie.HttpOnly = true; options.ExpireTimeSpan = TimeSpan.FromMinutes(30); options.SlidingExpiration = true; options.LoginPath = "/Account/Login"; options.LogoutPath = "/Account/Logout"; options.AccessDeniedPath = "/Account/AccessDenied"; options.Events.OnRedirectToLogin = context => { context.Response.StatusCode = 401; return Task.CompletedTask; }; }); Add the following code to the Configure method in the Startup.cs file: app.UseSession(); app.UseAuthentication(); app.UseMiddleware (); Create new SessionExpiredMiddleware.cs file: public class SessionExpiredMiddleware { private readonly RequestDelegate _next; public SessionExpiredMiddleware(RequestDelegate next) { _next = next; } public async Task Invoke(HttpContext context) { var sessionFeature = context.Features.Get (); if (sessionFeature == null || sessionFeature.Session == null) { await context.ChallengeAsync(); return; } await _next(context); } }

Thanks for your time and help but we don't have the startup.cs in core 6.0. Can you please provide me a running application with this functionality only in core 6.0

Bro! You have to follow 3 easy steps: 1. Create a new Razor page named "SessionExpired.cshtml" that will be displayed when the session expires. This page should include a message informing the user that their session has expired and providing a link to return to the login page. @page @model IndexModel Session Expired Your session has expired. Please login again . 2. In the Program.cs file, configure the session middleware to set the timeout for the session and to redirect to the SessionExpired page when the session expires. You can also set the cookie name and other options as needed. using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Builder; using Microsoft.AspNetCore.Hosting; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Hosting; using System; var builder = WebApplication.CreateBuilder(args); builder.Services.AddSession(options => { options.IdleTimeout = TimeSpan.FromSeconds(30); // Set the timeout for the session options.Cookie.Name = ".MyApp.Session"; // Set the name of the cookie }); builder.Services.AddControllersWithViews(); builder.Services.AddRazorPages(); var app = builder.Build(); app.UseSession(); // Use the session middleware app.Use(async (context, next) => { var session = context.Session; if (session != null && !session.IsAvailable) { // Redirect to the SessionExpired page if the session has expired context.Response.Redirect("/SessionExpired"); return; } await next(); }); app.UseStaticFiles(); app.UseRouting(); app.MapControllerRoute( name: "default", pattern: "{controller=Home}/{action=Index}/{id?}"); app.MapRazorPages(); app.Run(); 3. Finally, in your other Razor pages or controllers, use the session to store and retrieve data as needed. The session will automatically expire after the timeout period specified in the configuration. If the user tries to access a page with an expired session, they will be redirected to the SessionExpired page. public class MyController : Controller { public IActionResult Index() { // Set a value in the session HttpContext.Session.SetString("MyKey", "MyValue"); // Retrieve a value from the session var value = HttpContext.Session.GetString("MyKey"); return View(); } } DONE! Your users will be automatically redirected to the SessionExpired page when their session expires.
