Polymer Service Worker Not Caching And Maybe Not Fetching

[Darin Hensley]

I have this custom element which fetches the facebook profile pic(very small size) with url. I am using a service worker to intercept the call out and cache it. However, it does not seem to effective. The call out goes out over network with every page refresh. In addition, there is nothing in dev tools under local storage. I also tried cacheOnly and it still called out to the network for the url, so I know that the service worker platinum-sw-fetch is not effective.

Any suggestions on what I am doing wrong? If it did work, shouldn't I see something in local storage for dev tools? I do see the service worker itself in dev tools though.

<platinum-sw-register auto-register
                      clients-claim
                      skip-waiting
                      base-uri="../bower_components/platinum-sw/bootstrap">
  <platinum-sw-fetch
    origin="https://z-1-scontent.xx.fbcdn.net"
    path="/hprofile(.*)"
    handler="cacheFirst">
  </platinum-sw-fetch>
</platinum-sw-register>

Please disregard.... I realized this can not be done because of cross domain...even with the origin attribute.
