817691 - Reinstall a web app should refresh the browser cache

Status: RESOLVED WONTFIX

(Firefox for Android Graveyard :: Web Apps (PWAs), defect, P3)

Description

[Ian Bicking (:ianbicking)]

I've developed a webapp (http://xmasapp.ianbicking.org/install.html) and installed it as an app on Android (Nightly).  After updating the application on the server, I can't get any updates to appear on my device.

I've tried deleting and reinstalling the application (where by "deleting" I just removed the link from the home screen).  Nightly itself shows the updated version of the page.  I don't have any appcache setup on the app.

Ian - What was updated with the application? The manifest? JS?

Trying to better understand how to generally reproduce this (STR).

I updated the content of the front page, but not the manifest.

The headers on the content:   

  HTTP/1.1 200 OK
  Server: nginx
  Date: Thu, 06 Dec 2012 17:23:13 GMT
  Content-Type: text/html
  Content-Length: 37784
  Last-Modified: Mon, 03 Dec 2012 16:43:27 GMT
  Connection: keep-alive
  Expires: Fri, 07 Dec 2012 17:23:13 GMT
  Cache-Control: max-age=86400
  Accept-Ranges: bytes

The max-age is 24 hours (this is what Github Pages adds, and cannot be overridden).  The content persisted in my app longer than that.  A couple days later when I updated Nightly it appeared to clear that cache.

I think you could reproduce by creating an app, installing it, and updating the content of the app (on the server) and seeing that the content in the app has not changed.

Also I believe regardless of cache headers, when reinstalling the app the content it would be best to refresh the content.

Per bug 1235869, we're going to disable the Android web runtime, so we won't fix this bug in it.

(This is part of a bulk resolution of bugs in the Firefox for Android::Web Apps component, from which I attempted to exclude bugs that are not specific to the runtime, but it's possible that I included one accidentally.  If so, I'm sorry, and please reopen the bug!)
