Rails Render JSON - session loss?

I am trying to make some Ajax calls to a controller that responds with JSON.

if session[:user]
  render :json => "Some Data"
else
  render :json => "You are not logged in"
end

The first time this action is called by an offline user, everything is fine, and session[:user]- != nil. The second time he's called it nil!

So it seems that the rails are losing session as soon as I do render :json. I found out that within the first call, the rails redefine *_sessioncookies with a new one. As a consequence of the fact that the rails do not know about the original, autonomous session.

If I do not give the answer as JSON, everything works fine.

How to make rails set the same session file in displayed JSON pages, as in regular views?
