I want to read the content of some webpages and make some string

regular expressions, etc.).

StringBuilder htmlCode = new StringBuilder();

URLConnection conn = url.openConnection();
BufferedReader dis = new BufferedReader(new
String inputLine = "";
for(;;) {
      inputLine = dis.readLine();
        if (inputLine == null) break;

It works, but it is very, very slow comparing to browser. Do you know
any ways to speed it up??

Don't use a buffered reader, as you don't need to read it one line at a

        final URL url = new URL(adjustUrl(page));
        final HttpURLConnection connection = (HttpURLConnection)

        try {
            final InputStream is = connection.getInputStream();
            final Reader reader = new InputStreamReader(is);
            final char[] buf = new char[1024];
            int read;
            final StringBuffer sb = new StringBuffer();
            while((read = > 0) {
                sb.append(buf, 0, read);
        } finally {
