The following action redirects an HTTP If using rule priority, wildcard listeners should be defined a priority with a number greater than non-wildcard listeners, to ensure non-wildcard listeners execute prior to the wildcard listeners. The path pattern is applied only to the path of the URL, not to its query one of the strings matches the value of the HTTP header. If the listener protocol is TLS, you must deploy exactly one SSL server certificate on the listener. If you want end-to-end TLS encryption to the backend target, you must choose HTTPS within backend HTTP setting as well. HTTPS probes are the same as HTTP probes with the addition of a Transport Layer Security (TLS). the listener port for a configured listeners that are not new connections or part of an If a target group is configured with the TLS protocol, the load balancer establishes TLS connections with the targets using certificates that you install on the targets. The trigger can be an intermittent probe failure that causes the load balancer to mark down the appliance instance. include the cookie that it receives in subsequent requests to the load balancer.
