httphandler無法正常工作

Question

我試圖重定向用戶只有當用戶登錄到不同的頁面。我使用HTTPHandler來攔截此請求並重定向。用戶登錄後，控件不會返回到此HTTPHandler。任何意見或建議，

namespace NES.HiLo.Security 
{ 
    public class PallativeAuthenticationHandler : IHttpHandler, IRequiresSessionState 
    { 
     /// <summary> 
     /// You will need to configure this handler in the web.config file of your 
     /// web and register it with IIS before being able to use it. For more information 
     /// see the following link: http://go.microsoft.com/?linkid=8101007 
     /// </summary> 


     public bool IsReusable 
     { 
     // Return false in case your Managed Handler cannot be reused for another request. 
     // Usually this would be false in case you have some state information preserved per request. 
     get { return false; } 
    } 

    public void ProcessRequest(HttpContext context) 
    { 

     string UserName = ""; 
     int TSecUserID = 0; 

     HttpContext context2 = HttpContext.Current; 

     if (string.IsNullOrEmpty(context2.User.Identity.Name)) 
      UserName = "UNKNOWN"; 
     else 
      UserName = context2.User.Identity.Name.ToString(); 

     if (UserName != "UNKNOWN") 
     { 

      string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["NES.HiLo.Data.Properties.Settings.HiLoConnectionString"].ConnectionString; 
      using (SqlConnection connection = new SqlConnection(connectionString)) 
      { 

       connection.Open(); 
       SqlCommand command = new SqlCommand("Select tSec_UserId from dbo.HiLoUser where Username='" + HttpContext.Current.User.Identity.Name.ToString() + "'", connection); 


       TSecUserID = (Int32)command.ExecuteScalar(); 
       connection.Close(); 
       HttpContext.Current.Response.Redirect("http://www.google.com?retUrl=" + TSecUserID); 

      } 

     } 
     else 
     { 
      HttpContext.Current.Response.Redirect("~/Login.aspx?retUrl=" + HttpUtility.UrlEncode(context2.Request.Url.ToString())); 

     } 



    } 
}

Answer 1

你所面臨的問題有事情做與事實驗證Cookie只對指定的域是有效的：

<forms name="KFCSAUTH" 
    loginUrl="login.aspx" 
    protection="All" 
    slidingExpiration="true" 
    path="/" 
    domain=".scot.nhs.uk" /> 

也許只有當您在某個其他域中運行Web應用程序時纔會出現此問題。嘗試刪除domain屬性並查看問題是否仍然存在。
