title: Watir Webdriver Detection
body: <p>Is there a way to detect whether someone is conducting web testing using watir-webdriver on your site? I have read somewhere that it is fairly easy to detect watir/selenium, but I never managed to get more details about it.</p>
  
  <p>I have tried UserAgent detection, but that's not something very useful as far as it's easy to change it.</p>
