With PR#249 the AsseticBundle
(by default included in every symfony-standard-based Symfony2
application) supports the cache busting worker out of the box.
What happens: It will create different file names for different file contents, not only on the file name (At least it should, I
haden’t time to try it yet). This is cool, because now you don’t have to take care about cache invalidation for assetics assets yourself.
