行爲過濾器被解僱，但重定向是不會發生

Question

我發現這個代碼，當我的會話到期趕上：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Mvc; 

namespace SuburbanCustPortal.MiscClasses 
{ 
    public class SessionExpireFilterAttribute : ActionFilterAttribute { 

     public override void OnActionExecuting(ActionExecutingContext filterContext) { 
      HttpContext ctx = HttpContext.Current; 

      // check if session is supported 
      if (ctx.Session != null) { 

       // check if a new session id was generated 
       if (ctx.Session.IsNewSession) { 

        // If it says it is a new session, but an existing cookie exists, then it must 
        // have timed out 
        string sessionCookie = ctx.Request.Headers[ "Cookie" ]; 
        if ((null != sessionCookie) && (sessionCookie.IndexOf ("ASP.NET_SessionId") >= 0)) 
        { 
         ctx.Response.Redirect("~/Home/Login"); 
        } 
       } 
      } 

      base.OnActionExecuting (filterContext); 
     } 
    } 
} 

它發射沒有問題，但被調用動作仍在運行它的過程：

[Authorize] 
[SessionExpireFilter] 
public ActionResult PrePayment(PaymentModel.PrePayment model) 
{ 
    if (string.IsNullOrWhiteSpace(Session[SessionEnums.CurrentAccountGuid.ToString()].ToString())) 
    { 
    return RedirectToAction("AddCustomer", "Customer"); 
    } 

    if (TempData["ViewData"] != null) 
    { 
    ViewData = (ViewDataDictionary) TempData["ViewData"]; 
    } 

...

[SessionExpireFilter]是在此代碼運行，但然後將它與導致問題，因爲會話不再有效方法的其餘部分繼續進行。第一行PrePayment出現錯誤，因爲它正在返回。

不應該重定向阻止這種情況發生？

編輯**

我所做的修改建議，現在有：

命名空間SuburbanCustPortal.MiscClasses { 公共類SessionExpireFilterAttribute：ActionFilterAttribute {

public override void OnActionExecuting(ActionExecutingContext filterContext) 
    { 
     HttpContext ctx = HttpContext.Current; 

     // check if session is supported 
     if (ctx.Session != null) { 

      // check if a new session id was generated 
      if (ctx.Session.IsNewSession) { 

       // If it says it is a new session, but an existing cookie exists, then it must 
       // have timed out 
       string sessionCookie = ctx.Request.Headers[ "Cookie" ]; 
       if ((null != sessionCookie) && (sessionCookie.IndexOf ("ASP.NET_SessionId") >= 0)) 
       { 
        //ctx.Response.Redirect("~/Account/LogOn/"); 
        filterContext.Result = new RedirectResult("~/Account/LogOn"); 
        return; 
       } 
      } 
     } 

     base.OnActionExecuting (filterContext); 
    } 
} 

}

預付款被AccountScreen調用，看起來它正在重新加載後返回。

使用此：

filterContext.Result = new RedirectResult("~/Home/Login"); 
    return; 

相反的：

ctx.Response.Redirect("~/Home/Login");
