title: Server returned HTTP response code 503 for URL
body: <p>I'm able to access website kissmanga.com yet I can't access it via program. I fixed error 403 that I was getting before that but now I get error 503.</p>
  
  <pre><code>    URL url = new URL("http://kissmanga.com/");
      System.setProperty("http.agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.29 Safari/537.36"); 
      BufferedReader bf = new BufferedReader(new InputStreamReader(url.openStream()));
  
      String str;
      while((str = bf.readLine()) != null){
          System.out.println(str);
      }
  
  
   Error that I get:
  Exception in thread "main" java.io.IOException: Server returned HTTP response code: 503 for URL: http://kissmanga.com/

  <p>Okay this code works with one small annoying problem. I don't get full html but just 2/3 of it.</p>
  
  <pre><code>    HtmlUnitDriver driver = new HtmlUnitDriver();
      driver.get("http://kissmanga.com/");
      Thread.sleep(5000);
      System.out.println(driver.getPageSource());
      driver.quit();
  </code></pre>
