    摘要： Provided are a web-based traceback system and method using reverse caching proxy, which can effectively protect a web server against various attacks launched by illegitimate user by acquiring network information and location information of users who attempt to access the web server through an anonymous server, without a requirement of installing any agent program in the users' clients. The web-based traceback system may include a reverse caching proxy server receiving a hypertext transfer protocol (HTTP) packet transmitted to a web server by a client, analyzing the header of the HTTP packet and determining whether the client has attempted to access the web server through an anonymous server based on the results of the analysis; and a web tracking server generating a response page for the HTTP packet upon receiving the results of the determination performed by the reverse caching proxy server, inserting a tracking code in the response page, and providing the response page to the client through the reverse caching proxy server, wherein the tracking code is automatically executed in a web browser of the client and thus provides network information of the client to the web tracking server.
