title: set to localStorage from a server side language
body: <p>If it's possible to set a cookie from a server side language, is it possible for a server side language to store data in the localStorage property of a browser? I'm interested in doing it in Go but I suppose the principle would be the same in any language. Go has a <code>SetCookie</code>  to set a Cookie but not a function to set localStorage. Is there a way to implement it?  </p>
  
  <pre><code>    http.SetCookie(w, cookie)
  </code></pre>
