title: Is it possible to write a cookie from a google apps script from a google site?
body: <p>The following simple javascript code in a GAS gadget does not appear to work:</p>
  
  <pre><code>document.cookie="username=John Smith; expires=Mon, 31 Aug 2015 12:00:00 UTC; path=/";
  </code></pre>
  
  <p>Is this one of those sandbox things that I'm not allowed to do? If so, is there an alternative or workaround?</p>
