Rack middleware for iframe-transport hacks.
Get Rails to work nicely with jquery-iframe-transport. Post data to an iframe and retrive data from there is still the only reliable way to post file in a javascript application.

It wrap the response in a html. The original response is insert inside a <textarea> tag.
Since you can't get headers from an iframe post, metadata are exposed as 'data-*' attributes of the textarea tag.
> curl localhost:3000/api/2/account
{"message":"Unauthorized"}
> curl 'localhost:3000/api/2/account?X-Requested-With=IFrame'
<!DOCTYPE html><html><body><textarea data-status='401' data-statusText='Unauthorized' data-type='text/html'>{"message":"Unauthorized"}</textarea></body></html>

# config/initializer/iframe_transport.rb
require 'rack_iframe_transport'
