Thanks for the quick reply! Your suggestion works fine. Perfect for my low
traffic server with lots of small sites. I'll look into getting Apache to
manage redirects if (when!) it gets busier.
The redirect is useful as if a user comes to the www. version of the site
and then to the no www version they lose their session as the cookies don't
match. With your suggestion the session is maintained regardless of the URL
entered.
