AngularJS + GAE not updating HTML - html

Question

EDIT: Turns out the version being served was outdated - updating the version in app.yaml doesn't actually update the served version.
As the title says, I'm trying to upload changes to an AngularJS app to Google App Engine (Python, if it matters).
The referenced HTML files for each view however will not update and I'm not sure why.
Here's the app.yaml:
- url: /site/(.*\.(js|css|png|ico|txt))$
static_files: site/dist/\1
upload: site/dist/.*\.(js|css|png|ico|txt)$
login: required
secure: always
- url: /site/(.*\.html)$
static_files: site/dist/\1
upload: site/dist/.*\.html$
login: required
secure: always
expiration: '30s'
- url: /site/.*
static_files: site/dist/index.html
upload: site/dist/index.html
login: required
secure: always
And a couple of examples of HTML referenced in app.js:
// Routes
$routeProvider
.when('/users', {
templateUrl: 'users/users.html',
controller: 'UserCtrl',
activeTab: 'users',
reloadOnSearch: false
})
.when('/users/profile/:userId', {
templateUrl: 'users/profile.html',
controller: 'UserProfileCtrl',
activeTab: 'users'
})
.when('/users/new', {
templateUrl: 'users/create.html',
controller: 'UserCreateCtrl',
activeTab: 'users'
})
So the html is in dist/users/__.html or appropriate, with app.js residing under dist/
Updating these files, then doing a GAE update does not update the html. I've set a cache expiration of 30s, still not updating.
Is there anything I can do to force all html changes to be uploaded?
JS/CSS files have a version number appended to the end as part of the build process so they work fine, but as far as I can tell that's not possible to do for the html with angular routes.

Answer 1

Perhaps you previously had a longer cache setting for the .html files? In that case they could already be cached on the Google frontend servers. If you look at the response headers in your browser's network inspector you can see if they are indeed cached and perhaps what their age is. You might have to wait till they are evicted from the cache before you can see updates to them again.
In the mean time, try with different filenames and see if that does work.
Another trick you could try is to add a timestamp to the filename.
So instead of requesting 'users.html' you could request 'users.html?cachebuster=' + +new Date()
