Вот мой вариантик:
public void send(String message) {
String query = null;
try {
query = "id=" + id + "&arg=" + URLEncoder.encode(message, "UTF-8");
}
catch (UnsupportedEncodingException ex) {
return;
}
URL url = null;
try {
url = new URL(writeUrl);
}
catch (MalformedURLException e) {
return;
}
DataOutputStream out = null;
BufferedReader inBuff = null;
try {
url = new URL(writeUrl);
URLConnection conn = url.openConnection();
conn.setUseCaches(false);
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
out = new DataOutputStream(conn.getOutputStream());
out.writeBytes(query);
out.flush();
inBuff = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
while (inBuff.readLine() != null) {
}
}
catch (IOException e) {
}
finally {
if (out != null) {
try {
out.close();
}
catch (IOException e) {
}
}
if (inBuff != null) {
try {
inBuff.close();
}
catch (IOException e) {
}
}
}
}
Не знаю точно, как насчет прокси на клиентской стороне, но жалоб пока не было - работает на разных клиентах, вообщем, народ доволен.
