基于HTTP1.1的WEB信息还原关键技术研究

对因特网中一些重要数据信息进行还原和提取,是保证网络应用的健康发展和打击网络犯罪的一个重要手段。根据因特网中的实时网络数据大多基于HTTP协议进行构建与传输这一应用背景,针对HTTP1.1中增加的持续性连接(Persist Connection)与块编码(Chunked Encoding)技术,探讨了在新技术下的信息还原方法,实现了对某些应用场合所关心数据的还原、提取和存储。所给出的还原方法经实践验证,处理效率和效果达到了预期目标,对识别因特网中的不良网页信息具有较大的实用价值。

Research on WEB Information Extraction Technology based on HTTP 1.1 Protocol

To guarantee the normally development of network application and attack the crime of using network, one of the most important aspects is monitoring and restoring the HTTP information. As most network applications’ data transmission is now based on HTTP 1.1, this paper studies the extraction of WEB information that used Persist Connection and Chunked Encoding technologies which are added in HTTP 1.1, implementing the reduction, extraction and store of data that are concerned in some application fields. The result of the experiment shows that: both efficiency and effect of the process are achieved and has a great meaning in distinguish the information from the Internet.
