使用django或asp.net中的resume工具上载基于Web的大型文件

我们正在寻找一种开发基于web的应用程序的方法，该应用程序应该具有使用resume功能上载大文件（大小高达10GB）的功能

我们希望使用python/django或C#/asp.net开发此应用程序

如果您有任何建议，我们将不胜感激。

对于如此大的文件，使用浏览器的标准上载功能是相当疯狂的。对于这样的文件，您更愿意将ftp功能公开到一个磁盘上，在.NET中，您可以在该磁盘上有一个windows服务监视器来监视某个文件夹，如果有东西掉在那里，则相应地采取行动。NET有一个可用的工具来帮助您完成工作。

使用Java后端将支持任何大小的文件

您需要将上传部分移植到Django。应该是这样的。虽然这不做任何校验和验证
