I have a small problem with my DNN website.  Basically we're moving our old site over to DNN since MCMS is a terrible content management system and DD is great.  However since we already have an established website with a lot of marketing for it, I need to keep some static urls.  Currently we have 3 seperate site sections for our site.  Our main corporate page, and a USA and Canada page.  Here in lies our problem.

Our marketing materials tell our US residents to go to www.OurCompany.com/USA/  however the DNN address for that page is http://www.OurCompany.com/USA/tabid/821/Default.aspx

Is there a way I can redirect www.OurCompany.com/USA/ to point to the appropriate page?  I tried making an child site at that has the main page as a URL redirect, but that doesn't work.  The redirect is only placed on the link in the navigation bar.
Alternatively is there a module that can do this?  Or a module that will allow me to change the HTTP header for that single page, or maybe one that allows me to enter PHP or JavaScript so that I can redirect it via code.

Any help is greatly appreciated, this is a huge stumbling block for us and could prevent us from using DNN if not solved, which we really don't want to do since it's a great application.

Thanks
