我正在使用以下代码 (asp.net) 为用户显示 pdf：

Response.ContentType = "Application/pdf";
Response.AddHeader("Content-Disposition", "attachment; filename=thePdf.pdf");

//data contains a pdf created with iTextSharp
Response.OutputStream.Write(data, 0, datalength);
Response.End();

有时用户会出错。我无法重现该问题，但这是我在日志中看到的，似乎它总是 Mozilla 4 或 5 有问题：

Error Message: The remote server returned an error: (414) Request-URI Too Large.
Error Source: System

我还没有找到解决问题的方法，您对如何解决有任何想法吗？

错误消息是明确的Request-URI。问题似乎与您的回答没有任何关系；用于生成错误的 url 是什么？

HTTP错误分类如下：

1xx - Informational
2xx - Successful 
3xx - Redirection
4xx - Client error
5xx - Server error

您的 414 错误必须是客户端生成的错误，与您的服务器代码无关。您的浏览器发送的 URL 太大而无法由您的 Web 服务器正确处理。

那么，网址的最大长度是多少？
