This script produces a table, one row per HTTP cache file, sorted by
descending expiry date (freshest file at the top, oldest at the bottom).
TODO: only print "delete all stale entries" if there are stale entries.
Tricky (ugly) to do without putting the link after the list, which would
force users to scroll to the bottom to find it.
