Remove dead code for handling LogoutAction. Dead code starts wih: ''' # I think now that LogoutAction redirects to # self.base ([tracker] web parameter in config.ini), # this code is not needed. However I am keeping it # around in case it has to come back to life. # Delete if this is still around in 3/2018. # rouilj 3/2017. # # Note using this code may cause a CSRF Login vulnerability. # Handle the case where user logs out and tries to # log in again in same window. # The csrf token for the login button is associated # with the prior login, so it will not validate.
