# This package enables the server to return different version of a
# document depending on the domain where the client is. We use this
# package for serving Norwegian sites with Norwegian replies while all
# other sites get replies in English.
#
# When activated this package reads the file "domain.suffix" where it
# expects to find a mapping from various domain names to suffixes that
# the files should have. For instance a domain.suffix file that looks
# like this:
#
# .nr.no nynorsk
# .no bokmaal
# .se swedish
#
# And an HTTP client that runs on nora.nr.no and asks for
# http:/gisle.html makes the server return the first that exist
# of the following documents:
#
# gisle.nynorsk.html
# gisle.bokmaal.html
# gisle.html
