The HTTP server issues the queries and responds with the results, including meta information, such as response time. A implementation that uses CGI is included with the DNSViz source. This enables the client to issue arbitrary DNS queries from the perspective of a remote HTTP server.<br><br></div><div>Cheers,<br></div><div>Casey <br></div></div></div></div>
