Non-repeating information grab

I am trying to make a program that will grab information line by line from a .txt document on the web and one that will continue to do so as the information is updated. So far I have this code and it does grab it from the website line by line, but when I upload an updated .txt file with more lines, the program doesn't grab the new ones. How can I make it do that?

try
        {
            URL url = new URL("http://www.zachburtle.com/Ye.txt");
            URLConnection connection = url.openConnection();
            connection.setDoInput(true);
            InputStream inStream = connection.getInputStream();
            BufferedReader input = new BufferedReader(new InputStreamReader(inStream));
            
            String line = ".";
			int previousCount = 0;
            
            while(true)
            {
				int count = 1;
				line = input.readLine();
			
                while(line != null)
                {
					if (line != null)
					{
						previousCount = count;
						++count;
					}
					
					if(previousCount < count && line != null)
					{
						System.out.println(line);
					}
					
					line = null;
                }
            }
            
            
        }
