在权限过滤器里设置跳转，有时可以跳转有时无法跳转

代码如下：

public void OnAuthorization(AuthorizationContext filterContext)
{
//var current = JsonConvert.DeserializeObject<CurrentTraderModel>(SessionHelper.GetSession("Fex_CurrentTrader"));
var current = JsonConvert.DeserializeObject<CurrentTraderModel>(CooKies.GetCookies("Fex_CurrentTrader"));
if (current != null)
{
Dictionary<long, string> hOnline = new RedisCache().Get<Dictionary<long, string>>("Online");
if (hOnline != null)
{
if (hOnline[current.LoginNumber] != null)
{
if (current.LoginDateTime != hOnline[current.LoginNumber].ToString())
{
SessionHelper.SetSession("Fex_SingleLogin", "1");
SessionHelper.SetSession("FEX_token_u_t", null);
SessionHelper.SetSession("FEX_t_i_t", null);
SessionHelper.SetSession("FEX_t_i_LoginNumber", null);
SessionHelper.SetSession("BB_First", "0");
CooKies.SetCookies("Fex_CurrentTrader", null);
filterContext.Result = new RedirectResult("/Account/Signin?type=QuitLoginOther");
//filterContext.HttpContext.Response.Write("<script>location.href ='/Account/Signin?type=QuitLoginOther';</script>");
//filterContext.HttpContext.Response.End();
}
}
}
}
}
