Reading and writng at the same time through UrlConnection

Question

Hi,
I have written an applet that communicates with a servlet through a Urlconnection. However, the outputstream from the applet must be closed before the inputstream can receive info from the servlet. The coding is as follows :
try{
URL url = new URL("http://"+codeBase().getHost()+":8001/servlet/gameQuizServlet");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
conn.setInput(true);
conn.setUseCaches(false);
conn.setRequestProperty("Content-Type", "application/octet-stream");
out1 =new PrintStream(conn.getOutputStream());
out1.println("how are you");
out1.flush();
out1.close();
in1 = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((FromServer=in1.readLine())!=null) {
if the statement 'out1.close()' is below the 'in1.readLine()', the applet can't output the "how are you" to the servlet. (although the applet can receive info from the servlet through 'in1.readLine()).
The applet and the servlet have to communicate in an interactive mode. I have tried the command 'setAllowUserInteraction(true)' instead of 'setDoOutput(true)' but it doesn't work. How can I make the inputStream and outputStream in the Urlconnection active at the same time.
Best regards.

Thanks for your opinion, DrClap.
I've already written a server(using ServerSocket in server, Socket in applet) for this application but when internet user using brower behind the firewall, it stops the communications. Using HTTP is one of the ways to go through the firewall, but has limitation. Can I go through the firewall by other means?
