The Terrorist Detection System (TDS) is aimed at tracking down suspected terrorists by the content of information that they access. One requirement identified during the implementation of TDS was the need for a module able to intercept textual Web pages from the network traffic in real time. Online-HTML Tracer (OHT) is the module of TDS in charge of tracing HTML pages transferred on to the Web. The design considerations of OHT and its architecture are described. Initial evaluations of OHT were performed in a LAN environment.
