Rails - How to fake PUT or DELETE request using XDomainRequest in IE

Question

How can I fake a PUT or DELETE request using XDomainRequest in IE? Or do I need to use an iframe transport?

I'm trying to access a restful API that's setup for CORS. It works in all other browsers but I can't figure out how to fake the PUT/DELETE actions in IE. With XDomainRequest, custom headers are not allowed, so I can't add the HTTP_X_HTTP_METHOD_OVERRIDE header which supposedly tells Rails to recognize the _method=put parameter in the json data.

The best solution I could think of was to add two new member routes mapped to #update and #destroy:

resources :posts do
    member do
        post :revise, :action => :update
        post :annihilate, :action => :destroy
    end
end

which added these routes when you run 'rake routes':

    revise_post POST   /posts/:id/revise(.:format)     {:action=>"update", :controller=>"posts"}
annihilate_post POST   /posts/:id/annihilate(.:format) {:action=>"destroy", :controller=>"posts"}

---

Note that I originally tried this:

resources :posts do
    member do
        post :update
        post :destroy
    end
end

hoping that it would create these routes:

 update_post POST   /posts/:id/update(.:format)  {:action=>"update", :controller=>"posts"}
destroy_post POST   /posts/:id/destroy(.:format) {:action=>"destroy", :controller=>"posts"}

but instead it created:

POST   /posts/:id(.:format) {:action=>"update", :controller=>"posts"}
POST   /posts/:id(.:format) {:action=>"destroy", :controller=>"posts"}

which look like they are overlapping and you could never get to posts#destroy.
