title: Obscure URL to hide sensitive files and prevent bots/scrapers
body: <p>I am not talking about any <code>.htaccess</code> rewrite rules.</p>
  
  <p>I am working on a web app and I want to obscure URLs from bot/scrapers - it should be something like the <a href="https://stackoverflow.com/questions/26560279/method-to-obscure-url-from-bots-similar-to-tripadvisor-com">question asked here</a>.</p>
  
  <p>We need to make the URLs obscured like the approach used by Trip Advisor. I tried many solution including the one posted in the above mentioned questions but it doesn't work for me.</p>
  
  <p>For example we have URL like <code>example.com/file.php?u=jh843</code> and want to obscure it in a way that make it something like <code>LqMWJQiMnYeVtIJpEJCIQQoqnQQxGEcQQoqnQQeVtIJpEJCIQQoqnQ</code> or <code>example.com/eVtIJpEJCIQQoqnQ</code> - either way it will be good.</p>
