大文件上传类(演示版)：其实很简单，最主要是在web.config中把最大请求长度设大点就ok了。默认为4096-category upload large files (demo version) : in fact very simple. The most important thing is the sed had requested the maximum length of Tai point on the ok. The default is 4096

纯asp语言编写的无组件大文件上传，有进度条显示。-Asp net component written in a large non-file upload, a progress bar shows.
