Tomorrow I think I'll be adding this functionality to MovedObject. It 
redirects and gives the proper HTTP status code, so as to inform search 
engines and whatnot. The current release doesn't do subpaths, but the 
next one will.

There's also Rewriter and Redirector, but I never did figure out how 
they work, which is why I wrote MovedObject. Yes, it really was easier 
to write a new product than figure out the existing ones, at least in 
this case.
