Filter a matched web request based on protocol analysis

The web application of HTTP service holds the majority share of the traffic transported through web. A big flaw of online filtering affects data transfer throughput. The filter suffers from being poor to analyze HTTP traffic like html reconstruction, HTML encoding, analyzing HTTP, and so on. This paper presents a remedy to this issue by putting the filter engine in sniffer mode. By this way filtering process and data transfer acts independently. At the same time, the filter engine combines a novel high speed patterns matching algorithm with protocol analysis. It can get the special interesting network packets which can get more high efficiency.
