在iis中托管时，清除跨浏览器的缓存无法正常工作

Question

我想在按钮点击时使用asp.net应用程序清除客户端所有浏览器的缓存。当我们从visual studio运行时，它的工作正常。但问题是当我们将应用程序托管到IIS中时，它变得无法正常工作。

这是代码，我用来清除客户端浏览器的缓存

  [WebMethod]
        public static string DoClearCache()
           {
            HttpContext.Current.Session.Abandon();
            HttpContext.Current.Session["AEmail"] = null;
            HttpContext.Current.Session.Clear();
            ClearCaches();
            clearchachelocalall();
            return null;
           }

    public static void ClearCaches()
    {
        HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        HttpContext.Current.Response.Cache.SetExpires(DateTime.Now);
        //HttpContext.Current.Response.Cache.SetNoServerCaching();
        //HttpContext.Current.Response.Cache.SetNoStore();
        HttpContext.Current.Response.Cookies.Clear();
        HttpContext.Current.Request.Cookies.Clear();
    }


    private static void clearchachelocalall()
    {
        string GooglePath = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Local\Google\Chrome\User Data\Default\";
        string MozilaPath = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Roaming\Mozilla\Firefox\";
        string Opera1 = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Local\Opera\Opera";
        string Opera2 = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Roaming\Opera\Opera";
        string Safari1 = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Local\Apple Computer\Safari";
        string Safari2 = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Roaming\Apple Computer\Safari";
        string IE1 = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Local\Microsoft\Intern~1";
        string IE2 = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Local\Microsoft\Windows\History";
        string IE3 = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Local\Microsoft\Windows\Tempor~1";
        string IE4 = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Roaming\Microsoft\Windows\Cookies";
        string Flash = Environment.GetEnvironmentVariable("USERPROFILE") + @"\AppData\Roaming\Macromedia\Flashp~1";

        //Call This Method ClearAllSettings and Pass String Array Param
        ClearAllSettings(new string[] { GooglePath, MozilaPath, Opera1, Opera2, Safari1, Safari2, IE1, IE2, IE3, IE4, Flash });

    }


    public static void ClearAllSettings(string[] ClearPath)
    {
        foreach (string HistoryPath in ClearPath)
        {
            if (Directory.Exists(HistoryPath))
            {
                DoDelete(new DirectoryInfo(HistoryPath));
            }

        }
    }

    public static void DoDelete(DirectoryInfo folder)
    {
        try
        {

            foreach (FileInfo file in folder.GetFiles())
            {
                try
                {
                    file.Delete();
                }
                catch
                { }

            }
            foreach (DirectoryInfo subfolder in folder.GetDirectories())
            {
                DoDelete(subfolder);
            }
        }
        catch
        {
        }
    }

我真的在寻找你宝贵的建议。
