Between versions, eXo Platform makes various changes on various layers.
To avoid that browsers use cached assets and display old behavior,
a parameter exo.assets.version
is added in exo.properties file.
When is updated, his parameter allows to:
Enforce browsers to reload javascript and css.
Build eXo Platform urls for resources serving.
Avoid asking users to clear their browser's cache.
By default, this parameter is set to eXo Platform package version, i.e for the version 5.0.x it is set to 5.0.x.
# Assets versions used in static resources URLs. Useful to manage caches.
exo.assets.version=5.0.x
