title: Prevent any form of page refresh using jQuery/Javascript
body: <p>Once the user is on my page, I do not want him to refresh the page.</p>
  <ol>
  <li><p>Anytime, the user hits <kbd>F5</kbd> or refresh button on top. He should get an alert saying</p>
  <blockquote>
  <p>You cannot refresh the page.</p>
  </blockquote>
  </li>
  <li><p>Also if the user opens a new tab and tries to access the same url in prev tab he should get an alert</p>
  <blockquote>
  <p>You cannot open same page in 2 tabs</p>
  </blockquote>
  </li>
  </ol>
  <p>Anyway I can do this using JavaScript or jQuery? Point one is really important.</p>
