急 在线等！.NET获取不到客户端IP

[Coffcer]

AJAX中Request.ServerVariables["REMOTE_ADDR"].ToString()和Request.UserHostAddress获取到的都是虚拟主机的IP，在线等，网站因为这个全出错了..

一般用这个函数就可以了

private string GetClientIP()
  {
   string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
   if (null == result || result == String.Empty)
   {
    result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
   }


   if (null == result || result == String.Empty)
   {
    result = HttpContext.Current.Request.UserHostAddress;
   }
   return result;
  }

   return result;
  }

谢啦，果然"HTTP_X_FORWARDED_FOR"这个可以，“REMOTE_ADDR”获取到的都是虚拟主机的IP
