internet explorer - 在IE9中没有在iframe中发送Cookie

internet-explorer cookies (3)

如果有人试图为.NET应用程序解决这个问题

如Carlos所述，添加一个P3P标题

HttpContext.Response.AddHeader("p3p", "CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\"");

编辑：更好的是，如果你想把它放在Controller中，只需添加以下属性即可

public class IEP3PHeaderAttribute : FilterAttribute, IResultFilter
{
    public void OnResultExecuting(ResultExecutingContext filterContext)
    {
        // check if the user is using a IE based browser, add a p3p header if true and hasn't already been added
        if (HttpContext.Current.Request.Browser.Browser.ToUpper().Contains("IE"))
        {
            if (System.Web.HttpContext.Current.Response.Headers["p3p"] == null)
            {
                HttpContext.Current.Response.AddHeader("p3p", "CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\"");    
            }
        }
    }

    public void OnResultExecuted(ResultExecutedContext filterContext)
    {
    }
}

然后在你的控制器中，例如HomeController

[IEP3PHeader]
public class HomeController
{
   public ActionResult DoSomething() {};
   public ActionResult DoSomethingElse() {};
}
