          RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("http://www.dsii.net");
          if (dispatcher != null)
          dispatcher.forward(req, resp);

Use a HttpURLConnection:
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException  {
String forwardURL="http://www.yahoo.com";
URL url = new URL(forwardURL);
// establish the connection
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
// read server response
StringBuffer res = new StringBuffer();
String line;
while ((line = reader.readLine()) != null)
res.append(line);
if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) {
throw new IOException(connection.getResponseMessage());
response.setContentType("text/html");
response.setBufferSize(8192);
PrintWriter out = response.getWriter();
out.println(res.toString());
out.flush();
out.close();
}HTH
