/var/cache

The subdirectories of /var/cache are intended to store cached information.
Because /var/cache is generally not world writable, XDG recommends that applications store cached data in a location below the directorry pointed at by the environment variable XDG_CACHE_HOME (or ~/.cache if the variable is not set).
