上载过大文件时显示有意义的错误

伟大的资源!

我使用上面的链接实现了对上传到服务器的文件的捕获,这些文件太大,被重定向到默认错误页面

web.config->

    < customErrors mode="RemoteOnly" defaultRedirect="~/GenericError.htm" />

    protected void Page_Error(object sender, EventArgs e)
    {
        if (HttpContext.Current.Error is HttpException)
            if ((HttpContext.Current.Error as HttpException).ErrorCode == -2147467259)
            {
                Server.ClearError();
                Response.Redirect(@"~/FileSizeError.htm", false);
            }
    }

上面的答案在IIS 7.5上对我不起作用。我们最终得出以下结论:

void Application_PreSendRequestHeaders(Object sender, EventArgs e)
{
    if (
        Request.Headers["Content-Length"] != null && 
        int.Parse(Request.Headers["Content-Length"]) > 150000000 &&
        Request.RawUrl.EndsWith("/Release/ProjectReleases.aspx?Mode=Create"))
    {
        try
        {
            Response.Redirect("http://anyurl", true);
        }
        catch (HttpException ex)
        {
            if (ex.Message == "Maximum request length exceeded.")
            {
                Server.ClearError();
                Response.ClearHeaders();
                Response.Redirect("http://www.edward-williams.com", true);
            }
        }
    }
}
