我有一个注销操作方法。我已经设置了无缓存,但仍然从缓存带来的数据。这是我的方法:
public ActionResult Logout()
{
FormsAuthentication.SignOut();
// clear authentication cookie
HttpCookie cookie1 = new HttpCookie(FormsAuthentication.FormsCookieName, "");
cookie1.Expires = DateTime.Now.AddYears(-1);
Response.Cookies.Add(cookie1);
// clear session cookie (not necessary for your current problem but i would recommend you do it anyway)
HttpCookie cookie2 = new HttpCookie("ASP.NET_SessionId", "");
cookie2.Expires = DateTime.Now.AddYears(-1);
Response.Cookies.Add(cookie2);
Session.Abandon();
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
Response.Cache.SetNoStore();
Response.AppendHeader("Pragma", "no-cache");
return RedirectToAction("Login", "Account");
}
我点击登出,我被重定向到登录页面。然后,当我点击浏览器返回按钮时,我仍然可以看到经过身份验证的页面,但当我刷新时,我再次被重定向到登录页面。有人能告诉我我哪里做错了吗?
在您的actions中添加以下代码
// to clear cache problems
this.Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
this.Response.Cache.SetCacheability(HttpCacheability.NoCache);
this.Response.Cache.SetNoStore();
