You can delete non-default rules for a listener at any time. You cannot delete the default rule for a listener. When you delete a listener, all of its rules are deleted. The following action routes requests to the two specified audiences based on the weight of each audience. We can configure query string rules that can be used to route requests based on key-value pairs, as well as keys in request query strings. To route the request that contains a query string with the key “name” and the value “abc”, define a query string condition and action in the listener rules. If you want to configure routing based on the HTTP request method, the rules of the request method are useful. This rule includes the request request method and the next action if the rules are followed. On the menu bar, select the Edit Rules icon (the pencil). A forwarding action forwards requests to its target audience.
Before adding a redirect action, create the audience and add goals to it. For more information, see Create an audience. Why was it that when I added a redirect rule to my load balancer, the load balancer and audience were disassociated? It works well for before-type rules, but I can`t attach an audience to it for redirect ALBs. For example, we want to redirect our traffic from a host that needs to address example.com, and then we can add the rule for example.com and action to route the traffic to the target instance. If we have two applications with the addresses example1.com and example2.com, we can add two different rules for example1.com and example2.com with the actions to route traffic to their respective instances. You can also use an absolute path or other action with the rules. To add a forwarding action, select Add Action, select Forward To, and then select one or more audiences. If you have multiple audiences, select a weighting for each audience and optionally enable audience opt-in. If you enable audience opt-in and there are multiple audiences, you must also enable persistent sessions for audiences. To record the action, select the checkmark icon. For more information, see Transfer Actions.
When a fixed-response action is performed, the action and URL of the redirect target are recorded in the access logs. For more information, see Accessing Log Entries. The number of successful fixed response actions is indicated in the measure HTTP_Fixed_Response_Count. For more information, see Application Load Balancing Measures. This Terraform module provides a simpler and more declarative interface for creating load balancing listening rules that determine how the load balancer routes requests to its registered targets. It is an alternative to creating lb_listener_rule resources directly in Terraform, which can be handy when configuring listening rules in a Terragrunt configuration, for example. Audiences are a set of targets that allow you to deploy variants of feature indicators to a list of users in bulk. You can group goals into a group by selecting individual goals or setting rules that automatically assign goals to an audience. For example, you can joe@harness.io individual targets and add jane@harness.io to the internal QA user group, or set a rule that all emails ending in @harness.io are added to the internal QA user group. You set a default rule when you create a listener, and you can set additional non-default rules at any time.
You can include or exclude specific goals, or set rules to add goals based on conditions you define. Application load balancers provide native HTTP/2 support with HTTPS listeners. You can send up to 128 requests in parallel over an HTTP/2 connection. The load balancer converts them into individual HTTP/1.1 requests and distributes them to healthy targets in the target group. Because HTTP/2 uses front-end connections more efficiently, you may notice fewer connections between clients and the load balancer. You cannot use the push functionality of the HTTP/2 server. If you have a multi-audience forwarding rule and persistent sessions are enabled for one or more audiences, you must enable audience opt-in. When you create a listener, you define actions for the default rule.
Standard rules cannot have conditions. If the conditions of none of the rules in a listener are met, the action is performed on the default rule.
