Are these pages PHP? If so, there are some "special" things you need to do
to send all the correct headers (I don't know/understand enough to give you
anything more than that).

Sort of on topic, and just remembered, I have a similar thing with
www.example.com vs. example.com. I have a 301 redirect set up in .htaccess
but the engines refuse to update their index to the www and I cannot remove
the example.com from Google
