# Clear out cached entries - use low level disk removal, even though we
# are clearing results from caches_action, for several reasons:
# * We can't use expire_action here, as it doesn't seem to be
# compatible with the :only_path we used in the caches_action
# call.
# * Removing everything is simpler than having to get all the
# parameters right for the path, and calling for HTML version vs. raw
# attachment version.
# * We cope properly with filenames changed by censor rules, which
# change the URL.
# * We could use expire_fragment with a Regexp, but it walks the whole
# cache which is insanely slow
