今天是个好日子！
我正在研究我在网上免费找到的 ASP VB 脚本。它在我的 Web 服务器上运行良好，但该解决方案将仅使用原始文件名保存到 Web 服务器的目录。
我正在寻找可以传递 URL 的 ASP 文件上传器解决方案：
http://globalbanke.com/uploadFiles.asp?CustomName=Red
然后上传页面打开，用户可以加载文件，然后文件在服务器上保存为“红色”
我的网页托管：

Server.ScriptTimeout = 600

我正在使用 upload.save() 方法。这一行在这里：
filePath = path & request.querystring("CustomName")
这给了我一个服务器错误，但如果我将它更改为“test.txt”，它会保存它。
所以我的问题是，如何使用 URL 查询作为服务器的文件名？
这是 ASP 类方法
