System.Web.HttpException (0x80004005): Server cannot set status after HTTP headers have been sent.
   at System.Web.HttpResponse.set_StatusCode(Int32 value)
   at System.Web.Mvc.HandleErrorAttribute.OnException(ExceptionContext filterContext)
   at System.Web.Mvc.ControllerActionInvoker.InvokeExceptionFilters(ControllerContext controllerContext, IList`1 filters, Exception exception)

我的应用程序在Application_BeginRequest（）和Application_Error（）中设置了以下代码，用于设置状态代码。我不确定它是否与它有任何关系。

    protected void Application_BeginRequest(object sender, EventArgs e)    {
      Response.BufferOutput = true;

      //enforce HTTPS
      if (!HttpContext.Current.Request.IsLocal && !Request.IsSecureConnection )
      {
        bool addHttpsAttribute = true;
        foreach (Filter filter in GlobalFilters.Filters)
        {
          if (filter.Instance is RequireHttpsAttribute)
          {
            addHttpsAttribute = false;
            break;
          }
        }

        if (addHttpsAttribute)
          GlobalFilters.Filters.Add(new RequireHttpsAttribute());
      }
}

    protected void Application_Error(object sender, EventArgs e) {
      Response.BufferOutput = true;
      var httpContext = HttpContext.Current;

      var currentRouteData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(httpContext));
      var currentController = " ";
      var currentAction = " ";

      if (currentRouteData != null) {
        if (currentRouteData.Values["controller"] != null && !String.IsNullOrEmpty(currentRouteData.Values["controller"].ToString())) {
          currentController = currentRouteData.Values["controller"].ToString();
        }

        if (currentRouteData.Values["action"] != null && !String.IsNullOrEmpty(currentRouteData.Values["action"].ToString())) {
          currentAction = currentRouteData.Values["action"].ToString();
        }
      }

      var ex = Server.GetLastError();

      var controller = new myApp.Controllers.ErrorController();
      var routeData = new RouteData();
      var action = "OtherError";

      if (ex is HttpException) {
        var httpEx = ex as HttpException;

        switch (httpEx.GetHttpCode()) {
          case 404:
            action = "NotFound";
            break;

            // others if any

          default:
            action = "OtherError";
            break;
        }
      }

      httpContext.ClearError();
      httpContext.Response.Clear();
      httpContext.Response.StatusCode = ex is HttpException ? ((HttpException) ex).GetHttpCode() : 500;
      httpContext.Response.TrySkipIisCustomErrors = true;
      routeData.Values["controller"] = "Error";
      routeData.Values["action"] = action;

      controller.ViewData.Model = new myApp.Models.HandleErrorInfo(ex, currentController, currentAction);
      ((IController) controller).Execute(new RequestContext(new HttpContextWrapper(httpContext), routeData));

      Context.ApplicationInstance.CompleteRequest();
    }
