Use:
Document onBody Load should call:
setListDefaultOrRedirect('listboxID','www.domain.com')
if there is a dropdown list to sync the country dropdown list. If
there is no dropdown list then onBody just needs to call:
checkForRedirect('www.domain.com')
Direct anchor links to pages specific language pages can use
onclick="setLanguageCookie('[languagecode]')
where [languagecode]
is either fr or nl
Any language listbox should have entries indicating language name
and folder or script to run
options 0 = Turned off, do nothing, don't even record a cookie
1 = Record the cookie, but don't redirect anywhere
2 = Allow redirecting but always to home page
3 = Full redirection to deep link equivalent
