Originally I was going to have all the redirects, even domain redirects handled by ReDj. The reason for that is that I was created short names for articles and I was adding those 301's to the .htaccess file and it was getting unwieldy so I decided that having a software interface would make it easier to keep track of these.
So yes handle those domain level redirects in .htaccess then handle the rest with ReDj.
ReDj is regex driven however and what I wanted to do was create 200 redirects instead of 301's.
