Thanks again. I went through that page earlier but I'm not clear with
the procedures.

Sample that I did :

class FormHandler(webapp.RequestHandler):
  def post(self):
      if processFormData(self.request):
          self.redirect("/test.html")
      else:
          print 'Hello'

I failed to redirect. Error :

Note :  NameError: name 'webapp' is not defined
        It seems like I need to import some package..

Please advice me.
