text: Q:
  
  Maximum length of content?
  
  I'm trying to connect with a server using HttpURLConnection, but I have a problem with the PUT method.
  I need to send a String with 1500 characters (or more), but in this case the server produces a timeout and returns 500 - server internal error.
  If I send a String lower than 1400 characters, I have not problem and the server returns OK.
  My code is the following:
  public String connectToServer(String prototype) {
      String responseString = "";
  
      try {
          BufferedReader in = new BufferedReader(new InputStreamReader(openURLForInput(new URL(URL), USERNAME, PASSWORD, prototype)));
          String line;
          while ((line = in.readLine()) != null) {
              System.out.println(line);
              responseString += line;
          }
  
      } catch (IOException e) {
          e.printStackTrace();
          responseString = e.toString();
      }
  
      return responseString;
  }
  
  //-----------------------
  public InputStream openURLForInput(URL url, String uname, String pword, String content) throws IOException {
      HttpURLConnection conn = (HttpURLConnection) url.openConnection();
      conn.setDoInput(true);
      conn.setDoOutput(true);
      conn.setRequestProperty("Authorization", userNamePasswordBase64(uname, pword)); // I know this is OK
      conn.addRequestProperty("Content-type", "application/xml; charset=utf-8");
  
      //conn.setChunkedStreamingMode(8 * 1024);
  
      conn.setRequestMethod("PUT");
      conn.connect();
  
      OutputStream output = conn.getOutputStream();
      OutputStreamWriter osw = new OutputStreamWriter(output, "UTF-8");
      BufferedWriter writer = new BufferedWriter(osw);
      writer.write(content); // content length  > 1400 characters
      writer.close();
      output.close();
  
      int status = conn.getResponseCode();
      Log.i("STATUS", status + "");
      Log.i("STATUS_ERROR", conn.getResponseMessage());
  
      return conn.getInputStream();
  }
  
  I tryed adding the lines 
  conn.setFixedLengthStreamingMode(contentLength)
  conn.setChunkedStreamingMode(8 * 1024);
  
  But the server's answer is wrong anyway.
  UPDATE:
  I could detect the problem. For some reason, when I try to send large bodys in the request, the server produces a timeout but not with all networks, only with some networks. I use a secure conection  SSL, maybe this can bring problems?
  
  A:
  
  Maybe it's a network MTU problem, I'd say you investigate on that front.
  Here's a table relevant to windows:
  Network             MTU (bytes)

  16 Mbps Token Ring        17914
  4 Mbps Token Ring          4464
