title: Application with Just API calls
body: <p>I have an application which are just HTML Pages. This does API calls from another server to fetch/sends data. Here are my questions.</p>
  
  <ol>
  <li>How are we going to maintain the session of the logged in user? That
  is, how can we prevent him from accessing other pages without logging
  into the application. </li>
  <li>How do we maintain session timeout at the UI level</li>
  <li>Do we need to encrypt the data before sending it? If so how do we do it using Jquery?</li>
  </ol>
  
  <p>Kindly let me know these. Thanks.</p>
