Compression System, RokBooster
It differentiates between the pages so if you have a particular combination of scripts on one page, and a different combination on another, two files will be created and loaded independently, allowing your site to load much faster.
NOTE: Clearing the Joomla cache will remove the RokBooster compressed cache files causing them to regenerate on the next page hit
