Browser caching JSON responses and serving it to users, instead of HTML app

Some browsers (like and chrome on browser) show a JSON result on re-opening an app.

Not sure if this is the same issue, but if you close a resource tab, and re-open that tab, the fetched JSON always fails to parse for some reason.

I've added the "Cache-Control", "no-store, no-cache, must-revalidate, private" headers to both the single page app as individual resource.
