说明：  本文介绍应用层HTTP数据包的截获与还原技术的实现,并简要介绍其中所涉及的数据包截获、数据包分析、应用数据重组以及数据包解码等关键技术。该系统可以监听网管人员感兴趣的数据包，通过对其进行分析和研究，分析出其遵守的协议以及其应用层数据，恢复到被监视用户所看到数据的格式。该系统的实现，为网管人员有效地管理网络提供了一种直观的工具。
(This article describes the application layer HTTP packets intercepted and Restore Technology and a brief introduction of which involved intercepted packets, packet analysis, restructuring, as well as application data packet decoding key technologies. The system can monitor network packets of interest, through its analysis and research, analysis of its compliance with the agreement as well as its application layer data, back to being monitored by the user to see the data format. The realization of the system for the management staff to effectively manage the network provides a visual tool.)
