Rails 3 and octet-stream content-type

Hi,
i am migration an rails 2.3 application to rails 3, and i’m having some
problems with post requests with ‘octet-stream’ content-type.

The problem is that rails is not passing the octet-stream params to the
controllers. We have some mobile apps (J2ME) sending us post requests
with
octet-stream content-type. It used to work until i try to migrate our
back-end to rails 3. Now rails just ignores the parameters and sends
nothing
at all to the controllers.

Anyone have some idea why that’s happening?

Thank you
Dimas C.
