title: Cookies or Session on Google Apps Script Webservice
body: <p>I've created websites before where the server-side code has access to either Cookies on the browser or some sort of Session variables. I have not figured out how to do this with GAS. I can host a website with GAS, but I have no way of seeing the login session when a new page is loaded. How do I do this?</p>
  
  <p>I would expect to see this information in the doGet() event, like this:</p>
  
  <pre><code>function doGet(e){
    e.session.userid; //or something like this
  }
  </code></pre>
  
  <p>NOTE: Anyone can access my site, even anonymous. So I can't rely on Google logins.</p>
