title: redirect uri for browser based app
body: <p>I make a browser based app, which is entirely client-side, so I don't have to have any url, but only xml files (<code>manifest.xml</code>, <code>extractor.xml</code> and <code>gadget.xml</code> in my case) and deploy the application through Google Apps Engine (GAE). What and how should I supply in the <code>redirect uri</code> address?</p>
