a) If one node is down, the other will be elected for new traffic. b) If there is a session sticky cookie to one node, the user will receive an error (BAD GATEWAY) because nofailover is set. This parameter ensures that if a failure occurs on the sticky node, the user stays put. -- Daniel Ruggeri --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org For additional commands, e-mail: users-h...@httpd.apache.org
