Service workers

[PEM--]

The current v1 solution leverage HTTP 304 mecanisms to void reloading the app (the HTML payload as well as its JS & CSS assets) on browser that have hit the server.

As we detect the platform, we are able to modify the payload for browser that are service worker compatible: http://caniuse.com/#feat=serviceworkers

By doing so, these browsers would even not tried to send an HTTP HEAD request.
