URL url = new URL(urlStr);HttpURLConnection conn = (HttpURLConnection) url.openConnection();
// Cast shouldn't failHttpURLConnection.setFollowRedirects(true);
// allow both GZip and Deflate (ZLib) encodingsconn.setRequestProperty("Accept-Encoding", "gzip, deflate");
String encoding = conn.getContentEncoding();InputStream inStr = null;
// create the appropriate stream wrapper based on// the encoding typeif (encoding != null && encoding.equalsIgnoreCase("gzip")) {
inStr = new GZIPInputStream(conn.getInputStream());} else if (encoding != null && encoding.equalsIgnoreCase("deflate")) {
inStr = new InflaterInputStream(conn.getInputStream(),
new Inflater(true));} else {
inStr = conn.getInputStream();}conn.setRequestProperty ( "User-agent", "my agent name");
