从getInput / OutputStream（）获得的输入/输出流的关闭是否会影响底层Socket的重新创建？

Question

I've already looked through resources which describe specifics of work with HttpURLConnection as in Java so in Android (where there is not default implementation of working with connection pool) and my question is: if I close a stream gotten from HttpURLConnection , will the system create a new one Socket at a next time when I establish a HttpURLConnection with the same URL or it will try to use an exist one? Considering the following code:

private byte[] downloadText(URL url, String data) {
   OutputStream out = null;
   InputStream in = null;
   HttpURLConnection conn = (HttpURLConnection) url.openConnection();

   try {
      conn.setRequestMethod("POST");
      conn.setReadTimeout(20 * 1000);
      conn.setConnectTimeout(15 * 000);
      conn.setDoInput(true);
      conn.setDoOutput(true);
      conn.setRequestProperty("Content-Type", "application/json;charset=utf-8");

      byte[] payload = data.getBytes("utf-8");
      conn.setFixedLengthStreamingMode(payload.length);

      conn.connect();

      out = new BufferedOutputStream(conn.getOutputStream());
      out.write(payload);
      out.flush();

      final int responseCode = conn.getResponseCode();
      final String responseMessage = conn.getResponseMessage();

      is = conn.getInputStream();

      if((responseCode / 100) == 2 || responseMessage.equals("OK")) {
         return readFromStream(is);
      }
   } catch (IOException e) {
      Log.e(TAG, "Error occurred while trying to connect to the server" + e.toString());
   } finally {
      try {
         if(out != null) {
             out.close();
         }

         if(is != null) {
            is.close();
         }
      } catch(IOException e) {
         Log.e(TAG, "Error occurred while trying to close data streams" + e.toString());
      }
   }
}

Your question doesn't make sense. If there isn't a connection pool, there is no 'existing socket' to reuse.
