List params = new ArrayList();

params.add(new BasicNameValuePair("firstParam", paramValue1));

params.add(new BasicNameValuePair("secondParam", paramValue2));

params.add(new BasicNameValuePair("thirdParam", paramValue3));

OutputStream os = conn.getOutputStream();

BufferedWriter writer = new BufferedWriter(

new OutputStreamWriter(os, "UTF-8"));

writer.write(getQuery(params));

writer.flush();

writer.close();

os.close();

conn.connect();
