Rebuilding the HTTP flows from the sniffed trace is a very important step to understand the today's WWW (HTTP) traffic, including dynamic Web content and peer-to-peer traffic. To the best of knowledge, WebTACT is the first open source tool to reconstruct the total HTTP flows, including header and object parts, from tcpdumped data. WebTACT could be used to analyze HTTP traffic characteristics from dumped TCP traces.
is a free software developed
at Mobile and Internet Systems
Laboratory, Department of Computer Science,
Wayne State University. It is
developed under KDveloper IDE, on Linux Redhat platform. It is written
C++(g++ compiler). The key features of WebTACT include:
- WebTACT not only extracts the HTTP header information, but also reconstruct the HTTP objects and use their hash digest values to represent them in analysis;
- HTTP traffic pattern analysis in persistent TCP connections: our reconstructed HTTP flows provide easy way to identify the HTTP sessions in a consistent TCP connections and the necessary information to investigate their unique traffic patterns.
- Dynamic content classification: we study the different scenarios for dynamic and personalized web contents and define several classifications to identify these cases. Details can be found in our Technical Report MIST-TR-03-003.
Currently, WebTACT can extract the following important information from the traces collected by tcpdump :
- TCP connection's start time;
- request/response sides' IP address and port number;
- HTTP session's position in a pipe-line TCP connection;
- start time of curent HTTP session's request and the end time of response;
- request browser infomation;
- HTTP request method
- request URL;
- request and response HTTP version;
- request's total size;
- response header's size and response object size;
- response object type;
- request/response cookie's digest ;
- response object's digest hash value;
- The classification of dynamic Web content.
All these characteristics will be exported to the text format output file. The output file could be analyzed and got statistical results.
