Scott,
It looks like Rails is receiving an OPTIONS request and choking on it.
This is generally an indication of CORS taking place (on PUT/POSTs with
CORS, it first performs a "pre-flight" OPTIONS request to see if the
actual request is allowed). I'm not sure what kind of stuff you have
set up in your .htaccess, but either Apache should be completely
handling the OPTIONS request and not passing it through, or else you'll
probably want to let Rails know how to deal with those requests. I use
Rack::Cors and it works like a charm - it's middleware and intercepts
the CORS stuff in a way that's usually completely invisible to the rest
of the app.
