Microsoft ReportViewer:会话过期错误

Question

该项目是ASP.NET 2.0,我自己从来没有能够重现这一点,但我收到的电子邮件告诉我,它每周发生在客户身上很多次,通常是连续几次.

这是完整的错误:

例外细节:

Microsoft.Reporting.WebForms.AspNetSessionExpiredException:ASP.NET会话已过期

堆栈跟踪:

我们遇到了同样的问题.到目前为止,我们只在会话到期时才找到它,但是他们在浏览器中使用了后退按钮来执行激进的缓存,这很好.但即使主页没有,ReportViewer也试图刷新.所以,我们刚刚添加了一些hacky Global.asax错误处理:

protected void Application_Error(object sender, EventArgs e)
{
    Exception exc = Server.GetLastError().GetBaseException();
    if (exc is Microsoft.Reporting.WebForms.AspNetSessionExpiredException)
    {
        Server.ClearError();
        Response.Redirect(FormsAuthentication.LoginUrl + "?ReturnUrl=" + HttpUtility.UrlEncode(Request.Url.PathAndQuery), true);
    }
}
