Question

我在网站的不同部分使用ViewAsPDF和ActionAsPDF方法，并将代码部署到我们的生产服务器。当我访问单个服务器IP地址然后按预期打印PDF，但是当我使用在服务器之间进行负载平衡的URL时，PDF功能失败并出现以下错误：

Exception information:
    Exception type: Exception
    Exception message: Error: Failed loading page http://example.com/PDF (sometimes it will work just to ignore this error with --load-error-handling ignore)
Exit with code 1 due to network error: UnknownNetworkError

PDF生成的常见解决方案是将msvcp120.dll和msvcr120.dll文件添加到与wkhtmltopdf.exe相同的文件夹中，但这没有什么区别。
