Rails is single-threaded, so I don't have to worry about changing stuff around when a request is made, right? I'm going to be using ActiveResource, but don't know ahead of time what the class's site will be. So basically on every request I'll be changing it (if I need to). Is it okay to do that? Once a request is made, no other requests can use the process...so as long as I update MyARes.site I should be okay. Is there a better all around way to do it?

Seems like a fine approach to me, although I am not very familiar with ARes. Jamis just posted about setting the timezone per request, which has the same approach: [http://weblog.jamisbuck.org/2007/2/2/introducing-tztime](http://weblog.jamisbuck.org/2007/2/2/introducing-tztime)
