I have small test app:

Socket socket = new Socket("jeck.ru", 80);

PrintWriter pw = new PrintWriter(socket.getOutputStream(), false);
pw.println("GET /ip/ HTTP/1.1");
pw.println("Host: jeck.ru");
pw.println();
pw.flush();

BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));

String str;
while ((str = rd.readLine()) != null) {
    System.out.println(str);
}

It`s output:

    These numbers are a result of:

    Transfer-Encoding: chunked

    See Chunked transfer encoding for more details and links to specifications.
