X-Frame-Options in with torquebox-server

I'm struggling while getting a webpage running on my torquebox-server. The page itself is working fine, but to integrate this into another webiste I need to enable (or at least change them to another value) the X-Frame-options for the torquebox-server. I wasn' able to find something in the documentation, and there is also no part in the config file, which seems to be the correct place to change this. Has someone already tried this or got this running on torquebox? I would be very grateful, if someone could help me out.. Cheers Tim
