How can I have a naked domain reroute to another specific domain?

I have a naked domain dpau.org that I want to reroute to the subdomain www.dpau.org including any complicated paths that follow the request? For example, I want someone who navigates to http://dpau.org/开发者_开发问答artists to be redirected to http://www.dpau.org/artists

The reason for this is somewhat complicated, but basically I use google hosted sites and have all our sites mapped to www.dpau.org/whatev but obviously people will ignore this www subdomain and I need something to correct for this ignorance.

Any help is enormously appreciated and will help the at-risk teens who come to our school in downtown Denver to learn the arts for free. Thanks Stackers!

OK, I see now you're using Google Sites. It all depends on what DNS host you use.
