# Check that FrontPage extensions appear to be working on a specified host.
# Currently only checks that the hit counter is not returning an error.
#
# Probably not a good idea to use this on a host that someone's counting
# the hits on, so create a separate vhost for frontpage extensions testing,
# or just install the extensions on the default/root host for your server, and
# point it against that hostname, running it against all vhosts on a server is
# probably rather wasteful.
