REVERSE TRACKING SYSTEM FOR WEB BASE USING REVERSE CASHING PROXY

PROBLEM TO BE SOLVED: To provide a reverse tracking system and method using a reverse cashing proxy, allowing comprehension of actual network information and a position of a connection person through an anonymous server even without installing an additional agent program to a client, and preventing occurrence of a suffering in a Web server even when Web attack occurs by a malicious connection person. SOLUTION: This reverse tracking system includes: a reverse cashing proxy server analyzing a header of HTTP transferred to the Web server from the client to decide whether the client uses the anonymous server or not; and a Web tracking server generating an HTTP response page added with a tracking code and providing it to the client through the proxy server, when possibility/impossibility of the use to the anonymous server is notified from the proxy server. The tracking code is automatically executed in a Web browser of the client having received the response page to provide network information of the client to the Web tracking server.
