Cookies are not send

Hello!

In my production environment there are no cookies sent to the client
when using the session hash…

Here is the login function:

def check
u = User.first(:conditions => [“nick = ?”, params[:user]])

if (u != nil) && (u.pass == params[:password])
  session[:user] = u.nick
  session[:lastlogin] = u.lastlogin
  u.lastlogin = Time.current
  u.save
  flash[:notice] = I18n.t("user.login.succesfull")
  redirect_to :controller => "user", :action => "dashboard"
else
  reset_session
  flash[:error] = I18n.t("user.login.userOrPassWrong")
  redirect_to :controller => "user", :action => "login"
end

end

Yes I know it is not optimum but it fits my needs and is also on my
schedule to refactor :smiley:

In the development environment all works well as expected, in
production environment on localhost also, but when I deploy to my
engineyard for further testing, there are no more cookies sent to the
client.

I really dont know where to begin… Since it works with the same
config on the localhost but not on the yard (except the database
configs)
