在 asp.net mvc 中防止用户在注销后返回

Question

我已经尝试了所有可能的方法来防止用户在注销后返回。但是 none 起作用了。我试过了 -

Response.ClearHeaders();

Response.Cache.SetAllowResponseInBrowserHistory(false);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();
Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCach‌es);

Response.AppendHeader("Cache-Control", "no-cache"); 
Response.AppendHeader("Cache-Control", "private"); 
Response.AppendHeader("Cache-Control", "no-store"); 
Response.AppendHeader("Cache-Control", "must-revalidate"); 
Response.AppendHeader("Cache-Control", "max-stale=0");  
Response.AppendHeader("Cache-Control", "post-check=0"); 
Response.AppendHeader("Cache-Control", "pre-check=0");  
Response.AppendHeader("Pragma", "no-cache"); 
Response.AppendHeader("Expires", "Mon, 26 Jul 2000 05:00:00 GMT"); 

Response.Cache.SetCacheability(HttpCacheability.NoCache);  
Response.Cache.AppendCacheExtension("no-store, must-revalidate");
Response.AppendHeader("Pragma", "no-cache"); 
Response.AppendHeader("Expires", "0");

我在 chrome (v.56) 上测试过。以上代码无法阻止用户退出后返回

有什么想法吗？？

Answer 1

转到 Global.asax.cs 文件并使用下面给出的代码从应用程序中清除缓存（希望有帮助）-

protected void Application_BeginRequest()
{
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
    Response.Cache.SetNoStore();
}

将这行代码粘贴到您要防止返回的控制器上方

[System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]

喜欢

 [System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
    public ActionResult Logout()
    {
        FormsAuthentication.SignOut();
        Session["Username"] = null;
        Session.RemoveAll();
        Session.Abandon();

        return RedirectToAction("Index", "Login");
    }
