Hello I am developing a solution in MVC in first time so I am facing a big issue, When I logout from my application(mvc razor web application) it displays login page, but if i press browser back button it displays last screen, i don't want this, i want if i press back button it still display same login page. here is my code for logout
public ActionResult Logout() { Session.Clear(); Session.Abandon(); Session.RemoveAll(); FormsAuthentication.SignOut(); this.Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1)); this.Response.Cache.SetCacheability(HttpCacheability.NoCache); this.Response.Cache.SetNoStore(); return RedirectToAction("Login"); }

It happens because your browser cached the page on the client. The solution is to prevent the caching of that page(s), by forcing the browser to request a new page even when pressing Back button, instead of reading the saved one.
put session attribute check(ex. user object) in restricted page controller. invalidate the session after logout.
Master, I have used the code that to prevent the user from going back to previous pages after logout. function preventBack() { window. history. forward(); } setTimeout("preventBack()", 0); window.
I had this problem a while ago, disabling the cache for the entire application solved my problem, just add these line to the Global.asax.cs file
protected void Application_BeginRequest() { Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1)); Response.Cache.SetNoStore(); } Hope this helps.

You need to add the cache META Tag for all the last page you visited
So add this for all the pages, by making a CustomAttribute like [NoCache] and decorate
public class NoCacheAttribute : ActionFilterAttribute { public override void OnResultExecuting(ResultExecutingContext filterContext) { filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1)); filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false); filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache); filterContext.HttpContext.Response.Cache.SetNoStore(); base.OnResultExecuting(filterContext); } } public class AccountController : Controller { [NoCache] public ActionResult Logout() { return View(); } } Or try it with javascript on the page like
<SCRIPT type="text/javascript"> window.history.forward(); function noBack() { window.history.forward(); } </SCRIPT> <BODY onload="noBack();" onpageshow="if (event.persisted) noBack();" onunload=""> If you love us?
