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");
