POST request processed as a GET in Heroku

I have a strange case. I have a RoR application that provides a REST API with which I connect from a Java application.

I develop RoR locally and deploy it in Heroku.

No matter how (I tried to use Java APP, Mozilla REST client, etc.), I try to send an HTTP POST request that should be processed by creating an action in the api controller. On the local host - everything works as expected. At Heroku env, the POST request is considered a normal GET.

Here are my routes for this resource:

        api_v1_items GET    /api/v1/items(.:format)                            api/v1/items#index {:format=>:json}
                     POST   /api/v1/items(.:format)                            api/v1/items#create {:format=>:json}
         api_v1_item GET    /api/v1/items/:id(.:format)                        api/v1/items#show {:format=>:json}
                     PATCH  /api/v1/items/:id(.:format)                        api/v1/items#update {:format=>:json}
                     PUT    /api/v1/items/:id(.:format)                        api/v1/items#update {:format=>:json}
                     DELETE /api/v1/items/:id(.:format)                        api/v1/items#destroy {:format=>:json}

Therefore, I am trying to execute a POST request on /api/v1/items, passing all the necessary parameters.

In localhost, the answer is correct:

Started POST "/api/v1/items?token=l4XOHrhDApPqTp1u4TxBjQ" for 127.0.0.1 at 2014-05-15 22:11:49 +0200
Processing by Api::V1::ItemsController#create as JSON
Parameters: {"height"=>10.0, "item_name"=>"Super item", "width"=>20.0, etc...

However, the same request quit at Heroku, it was considered as GET:

2014-05-15T20:27:58.137541+00:00 app[web.1]: Started GET "/api/v1/items?token=iEdDkDLiDUlWi0mDbr6XYw" for 89.74.57.51 at 2014-05-15 20:27:58 +0000
2014-05-15T20:27:58.223620+00:00 app[web.1]: Processing by Api::V1::ItemsController#index as JSON

I had the same problem when sending a POST request to a hero using HTTP instead of HTTPS. Every time heroku redirected my POST requests as GET requests. After I updated the URL to use HTTPS, my POST requests were redirected to heroku as POST, not GET, resolving the problem. The redirection issues mentioned in previous posts are probably the main cause of the problem I am having.
