IIS有默认的请求超时、程序池也有内存及CPU的限额设置== --------------------编程问答-------------------- 应该不是代码问题吧，该关闭的都关了，以前是用的FCK插件添加视频，现在直接用的上传控件 --------------------编程问答-------------------- 请求超时120S --------------------编程问答-------------------- 上传大小3G，超时120S 还要修改什么， --------------------编程问答-------------------- 如果你硬要用http上传，需要修改配置文件里最大上传限制
以及Server.ScriptTimeout = 600;
默认是90秒，设定的时间内没有上传完毕请求将超时，上传失败，这段时间的连接对服务端而言是一种累赘
如果文件过大，建议用ftp并且断点续传
--------------------编程问答-------------------- 上传是文件不是太大，100M。配置也改了，还是会出现错误， --------------------编程问答-------------------- 你有监控服务端的负荷吗，比如内存、CPU、出错次数==
假如有好几个人同时在上传呢？ --------------------编程问答--------------------
期待一下，没接触过视频的
