This module stores generated css/js optimized assets to the database, and recovers them to disk when missing.

It is intended to supplement the core patch Make css/js optimized assets path configurable in a multi-webhead architecture.

Why?

In a briefly way: Drupal core generates css/js optimized assets only in the first page render after a cache rebuild. So, if an asset is missing on disk after generation, Drupal is unable to regenerate it unless a cache rebuild is performed again.
