HTTP persistent connection

Question

Hello,
I know this subject has already been touched but I did not manage to find a practical solution.
I would like to send more than one http request (and check the response) to the same URL without having to reopen a new HttpURLConnection each time. The following piece of code does not seem to give any error but the server does not seem to receive more than one request. Could you give me any help ??
Thanks,
Francesco.
public void exec() {
try {
url = new java.net.URL(m_hostURL);
connection = (java.net.HttpURLConnection)url.openConnection();
connection.setRequestProperty("connection", "Keep-Alive");
//set the output to true
connection.setDoOutput(true);
out = new java.io.OutputStreamWriter(connection.getOutputStream(), "ASCII");
for (int i=1; i<= 10; i++) {
//place request in output stream
out.write("hello world!!");
out.flush();
//send request and receive response code
System.out.println(" Code : " + connection.getResponseCode());
out.close();
connection.disconnect();
} catch (Exception e) {
System.err.println("ERROR: Failed to send to URL - " + m_hostURL);
e.printStackTrace();

I also have been surfing the web to find out how to implement
an applet-to-servlet communication link over a persistent http connection.
There is a working implementation available for download at
http://www.ustobe.com/
After clicking on the 'news' item in the menu, there are links
available to download HttpKeepalive.java, with javadoc explaining
how to use this class.
