Abstract

A system and method for auditing network applications captures transmissions during a user session between a client and a server. An auditor capture filter captures and stores each request from the client and each response by the server to each request in an auditor storage. An auditor analyzer may use the captured requests and the captured responses to visually recreate the user session to thereby analyze what transpired during the user session.
