Hello Nathan,
Here is the code:

// If you have fast and working code for querying whois (I don't think it is
going to be conceptually
// different), could you please send it to [EMAIL PROTECTED] .
// PS> A conservative estimate is ~250 concurrent users, so I need to make
it fast.

public class WhoisSuccess1 extends HttpServlet {
public void init(ServletConfig config) throws ServletException {

public void doGet (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/html");
String dome = req.getParameter("dome");
String inner = dome;
String whoisIn = "";
String whoisFull = "";
Socket sock;
sock = new Socket("rs.internic.net", 43); // can be "internic.net" or
"whois.internic.net"
BufferedReader in = new BufferedReader(new
InputStreamReader(sock.getInputStream()));
PrintStream outs = new PrintStream(sock.getOutputStream());
outs.print(inner);

out.println("<h1>" + whoisFull + "</h1>");
out.println("</body></html>");
}// end doGet
