I am using sockets to create a POST request to a given server. The response comes back mostly ok, and I'm using an InputStream with an encoding of "UTF-8" to read the response from the server. Most of the response makes sense and I'm able to view the HTML correctly, however, seemingly at random, I see codes such as "1ffa", "6e8", "1972", "90", "0" come up as single lines on the response as I'm reading it in. Here's how I create and read the response.
String hostname = "server";
SocketFactory socketFactory = SSLSocketFactory.getDefault();
Socket socket = new Socket(hostname, 8080);
// Create streams to securely send and receive data to the server
InputStream in = socket.getInputStream();
OutputStream out = socket.getOutputStream();
PrintWriter writer = new PrintWriter(out);
writer.println("POST /handlerServlet http/1.1");
writer.println("Host: " + hostname);
String parameters="params=" + URLEncoder.encode("paramsToEncode", "UTF-8");
writer.println("Content-Length: " + parameters.length());
writer.println("Content-Type: application/x-www-form-urlencoded");
writer.println("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
writer.println("Keep-Alive: 115");
writer.println("Connection: keep-alive");
writer.println("\r\n" + parameters + "\r\n");
writer.flush();
// Read from in and write to out...
String input = "";
BufferedReader reader = new BufferedReader(new InputStreamReader(in, "UTF-8"));
StringBuffer result = new StringBuffer();
boolean startWriting = false;
FileOutputStream outStream1 = new FileOutputStream(new File("/file1.txt"));
Writer outWriter = new OutputStreamWriter(outStream1, "UTF-8");
while ( (input = reader.readLine()) != null) {
result.append(input);
outWriter.write(input + "\n");
result.append('\n');
}
System.out.println(result.toString());
outWriter.close();
// Close the socket
in.close();
Does any one have any clue as to why I would see characters like this?

as you can see, having these characters appear in random locations can cause some hecktick behavior on the HTML code.
Thanks.

Do you get a header in your response that says something like this?
Transfer-Encoding: chunked
In this case, it's most likely due to HTTP Chunked Transfer Encoding. It's normal.
