推荐答案

您需要在网页中跟踪客户端代码下载并报告给它认为已完成的服务器.

这确实是一个糟糕的想法.如果用户丢失了下载的文件并需要另一个副本该怎么办?他们被搞砸了，这对业务不利.通常，如果有人在线购买了一些可下载的内容，则可以允许他们再次下载.

You would need client-side code in the web page tracking the download and reporting back to the server that it thinks it''s complete.

This is a really BAD idea to implement. What if the user loses the downloaded file and needs another copy? They''re screwed and that''s not good for business. normally, if someone pays for some downloadable content online they are allowed to come back and download it again.
