Tomcat Inputstream Returns -1

I am trying to get content using Java's inputstream.  

When I try to get content from yahoo, sometimes the inputstream returns an immediate -1.  This happens when running in a servlet running on tomcat.

I ran a test prototype without the web server, tomcat 5.x, it works just fine.  Returns content.

Why would running in a web server make a difference?

I tried using the URL class but did not get the behavior I need.  I need the exact same behavior as a browser so I have to use the Socket class. I've been posting questions and feedback has been to use the URL class.  I can't use the URL class cuz it doesn't give the same behavior as a browse.r
OutputStream os = null;
        ByteArrayOutputStream byteContainer = new ByteArrayOutputStream();
        try {
            Socket socket = new Socket("www.msnbc.msn.com", 80);
 
            String r = new String("GET / HTTP/1.1\n" +
                    "Host: www.msnbc.msn.com\n" +
                    "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12\n" +

            System.out.println("Connecting using the following get request: " + r);
 
            os = socket.getOutputStream();
            boolean autoflush = true;
            PrintWriter out = new PrintWriter(socket.getOutputStream(), autoflush);
            out.println(new String(r));
            out.println('\r');
            out.println('\n');
            out.flush();
            socket.shutdownOutput();
 
            // Read the response
            byte[] b = new byte[1024];
            InputStream in = socket.getInputStream();
            int i = in.read(b);
            while (i != -1) {
                byteContainer.write(b, 0, i);
                i = in.read(b);
                System.out.println("i: " + i);
            }
 
            socket.close();
            in.close();
            out.close();
            os.close();
 
            byte[] content = byteContainer.toByteArray();
            byteContainer.close();
 
        } catch (IOException ex) {
            ex.printStackTrace();
        }

then use HttpClient, it gives you greater control over what is sent.
nothing is going to give you exactly the samer behaviour as a browser though, plus every browser is different.
