我正在制作一个应用程序，其中我们可能有 5 或 6 个步骤。在第一步中，我将选择我需要的报告并保存并继续......它会让我进入第二步......就像这样......我的问题是根据功能，当我点击浏览器后退按钮时，我需要去到上一页。当我再次按下它时，它必须转到我的主页，但它会将我重定向到上一页。它适用于除 chrome 和 safari 之外的所有浏览器。我正在插入我的代码以供参考..请帮我解决这个问题..

protected void Page_Load(object sender, EventArgs e)
{

    DisableHistory();
    lnkBackBrowse.Style["visibility"] = "hidden";
    if (Session["UserId"] != null)
    {
        if (Convert.ToInt32(Session["UserId"].ToString()) == 0)
        {
            TopNavigationMenu.Style["visibility"] = "hidden";
            NavigationMenu.Style["visibility"] = "hidden";

            if (!Request.Url.ToString().Contains("Home") && !Request.Url.ToString().Contains("SaveandLogout"))
                Response.Redirect("Home.aspx");
        }
        else
        {
            TopNavigationMenu.Items[0].Text = "Welcome :" + Session["UserName"].ToString();
            TopNavigationMenu.Style["visibility"] = "visible";
            NavigationMenu.Style["visibility"] = "visible";

            if (Session["FirstTimeLogged"] != null && Convert.ToBoolean(Session["FirstTimeLogged"]) == true)
            {

当您按下后退按钮时，这些浏览器会向您显示缓存的内容。

您可以调试和检查，您的服务器没有被击中。此会话代码将不起作用。

您可以告诉浏览器不要缓存该页面。这样，如果用户想要返回，他将不得不重新加载内容。
