Subject: calling child from parent

hi -

i understand super passes method calls up to the parent.

is there a way to call down to the child instance, to a different method?

I realize i could pass a function block up to super, and then use
yield to call back to the child, but i want to hide this complexity
from my child classes.

the setup is something like this:

class Webserver < HTTPServlet::AbstractServlet
    def do_GET(request, response)
       // here i want to hand off to the instance child servlet to
handle the response
       child.render()
   end
end


class Servlet1 < Webserver
   def render
     // do some stuff
  end
end

etc for other servlets.

I guess the other way is to instantiate the right child servlet in the
webserver, but this means i dont get access to super methods...

tx,
