Method and system for reducing WEB type application contents

Abstract

The invention discloses a method and a system for efficiently reducing WEB type application contents, which belong to the field of network communications. The method comprises the following steps of: 1) writing a template file according to the characteristics of WEB type application data packets; 2) reading and resolving the template file to form a template linked list; 3) resolving the header ofa hypertext transport protocol (HTTP) data packet to obtain header contents such as a uniform resource locator (URL), HOST and the like; 4) comparing resolved fields such as the URL, the HOST and thelike with fields such as a URL, a HOST and the like described by a template to find out matched templates; 5) extracting corresponding contents from an HTTP content part by using keywords defined in the successfully matched templates; and 6) formatting the extracted contents and outputting. The system comprises a data packet input module, a protocol recognition module, a template introducing module, a template searching and content extracting module and an output module. By the method and the system, the WEB type application contents can be efficiently reduced, and protocols can be easily increased by adding templates.

Description

technical field [0001] The invention belongs to the field of data communication, and relates to a method and system for efficiently restoring WEB application content. Background technique [0002] WEB applications are based on the HTTP protocol, and there are many types, including currently popular social networking sites, email sites, BBS sites, blog sites, game sites, search sites, online chat sites, etc. Restoring the login and content of WEB applications plays a very important role in network security and pornography monitoring. The traditional protocol restoration method is based on data packet search, and analyzes each HTTP data packet in order to analyze the corresponding application protocol, and analyze the login information, post information and other content in the HTTP content field. In a network environment with small network traffic and few types of WEB applications, the method based on data packet search is also feasible, but today's network traffic is increa...

AI Technical Summary

Problems solved by technology

In a network environment with small network traffic and few types of WEB applications, the method based on data packet search is also feasible, but today's network traffic is increasing, and the proportion of WEB applications in all network applications is getting higher and higher , and the efficiency of the method based on data packet search is getting lower and lower. At the same time, the workload of the personnel engaged in protocol restoration is becoming more and more heavy. Therefore, the traditional method of protocol restoration can no longer meet the needs of today's network environment.
