Asp.net mvc 4 如何获取MVC项目属性中定义的SSL URL？

我启用了SSL，我正在尝试编写自己的

requireHttpAttribute

，以便于使用IIS Express进行测试。当它重定向时，它重定向到端口44301，但我不想硬编码，我想从现有配置中读取

public sealed class RequireHttpsAlternativePortAttribute : RequireHttpsAttribute
{
    protected override void HandleNonHttpsRequest(AuthorizationContext filterContext)
    {
        base.HandleNonHttpsRequest(filterContext);

        //alter the port in the base classes result
        var baseRedirect = filterContext.Result as RedirectResult;
        if (baseRedirect == null)
        {
            throw new Exception("No redirect was suppied from the base class");
        }

        var builder = new UriBuilder(baseRedirect.Url);
        var targetPort = 44301; //need this from settings
        if (builder.Port == targetPort) return; //already correct port

        //change the port
        builder.Port = targetPort;
        var redirectResult = new RedirectResult(builder.ToString());
        filterContext.Result = redirectResult;
    }
}

44301在SSL URL下的MVC项目属性中定义。我的问题是，这在运行时的任何地方都可以访问吗
