摘　　要：分析了在网络环境中基于HTTP协议进行多线程下载和断点续传的原理和实现方法,给出了一个多线程下载工具的实现。该下载工具的设计基于VC++的多线程技术和CSocket编程,采用线程的创建和管理、各下载线程字节数分配等关键技术,实现了从Web服务器到客户端的多线程下载及断点续传。This paper analyses the principle and implement method of multi-thread downloading and broken-point continuinglytransferring based on HTTP on Internet. The realization of a multi-thread downloading tool is proposed. This downloading tool is designed based on multi-thread technology and CSocket programming, and it adopts the key technology, such as creating and managing multi-thread, allocating size of each thread, etc. It achieves the multi-thread downloading and broken-point continuingly- transferring from Web server to client.
