> The gadget server creates iframes that point to a "jail domain". The iframes include gadget content as well as boilerplate Javascript.
> To improve browser latency, the iframes should have long cache timeouts. However, this conflicts with our goal of allowing developers to control the refresh rates of their gadget.xml files. Therefore, the iframe URLs should include a hash of their contents, and the page itself should have a long expiration time. This means that the browser will reload the iframe only when the gadget.xml is changed.
