Servlet, change URL parameters

Hi,
I'm connection to a URL in a servlet (check the code attached).

I wonder if there is any way to make multiple connection to the same URL and to pass different request parameters ... without creating a new connection.

In my example, I want to change what I write in osw.write ....

thanks

private static void connect (boolean GET_METHOD) throws Exception
    {
        String parameters="firstName=Paz";
        String urlString="http://localhost:8080/Research/SimpleServlet?";
 
        if (GET_METHOD)
            urlString += parameters;
 
 
        URL url = new URL (urlString);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setAllowUserInteraction (true);
        conn.setDoOutput(true);
 
        if (!GET_METHOD)
        {
            OutputStream osw = (OutputStream) conn.getOutputStream();
            osw.write (parameters.getBytes());
        }
        BufferedReader respContent = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        PrintWriter display = new PrintWriter(System.out);
        String respLine;
        while( (respLine = respContent.readLine()) != null)
        {
            display.println(respLine);
        }
        display.flush();
        respContent.close();
        conn.disconnect();
    }
