How to emulate MSIE or Netscape in URLConnection?

Hello!

I have a spider program project and there are websites
wherein I get a different webpage when using MS Internet
Explorer compared to using my Java code which
looks like the ff:
   URLConnection uc = new URLConnection("www.test.com");
   InputStream is = uc.getInputStream();
   int b = is.read();
   String pagestr = new String();
   while (b != -1){
      pagestr += /* concatenate all the read bytes */
      b = is.read();
   }

The Java code above usually gets an error message
webpage.  It's like the HTTP server detects what type of
browser is accessing their pages.  If it's not Mozilla
compatible then it gives an error message webpage.

How do I write my Java code so as the webserver thinks
that my Java code is a Mozilla compatible browser?

I've seen a couple of forum discussions in java.sun.com
about the GET header their getting but I don't know how
to make Java code to do what their discussing.

Thanks in advance!

Hi.
You can try something like this :

    HttpURLConnection connection = (HttpURLConnection)url.openConnection();
    connection.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible;MSIE 5.01; Windows NT 5.0)");
