Adding a Forwarding Policy ========================== Function ^^^^^^^^ This API is used to add a forwarding policy. Constraints ^^^^^^^^^^^ The protocol of the listener to which requests are redirected can only be HTTPS. The listener associated with the forwarding policy cannot be any listener added to other load balancers.

This | | | | | parameter is available only | | | | | for dedicated load | | | | | balancers and will take | | | | | effect when | | | | | **enhance_l7policy_enable** | | | | | is set to **true**. If this | | | | | parameter is passed and | | | | | **enhance_l7policy_enable** | | | | | is set to **false**, an | | | | | error will be returned. For | | | | | shared load balancers, this | | | | | parameter is not supported. | | | | | If it is passed, an error | | | | | will be returned. | | | | | | | | | | A smaller value indicates a | | | | | higher priority.

If | | | | | forwarding policies use | | | | | the same domain name, | | | | | their priorities follow | | | | | the order of exact match | | | | | (**EQUAL_TO**), prefix | | | | | match (**STARTS_WITH**), | | | | | and regular expression | | | | | match (**REGEX**). If | | | | | prefix match is used for | | | | | matching, the longer the | | | | | path, the higher the | | | | | priority. If a | | | | | forwarding policy | | | | | contains only a domain | | | | | name without a path | | | | | specified, the path is | | | | | **/**, and prefix match | | | | | is used by default. | | | | | | | | | | - If | | | | | | | | | | **enhance_l7policy_enable** | | | | | is set to **true** and | | | | | this parameter is not | | | | | passed, the priority | | | | | will set to a sum of 1 | | | | | and the highest priority | | | | | of existing forwarding | | | | | policy in the same | | | | | listener by default. | | | | | There will be two cases: | | | | | a) If the highest | | | | | priority of existing | | | | | forwarding policies is | | | | | the maximum (10,000), | | | | | the forwarding policy | | | | | will fail to create | | | | | because the final | | | | | priority for creating | | | | | the forwarding policy is | | | | | the sum of 1 and 10,000, | | | | | which exceeds the | | | | | maximum. In this case, | | | | | please specify a value | | | | | or adjust the priorities | | | | | of existing forwarding | | | | | policies. b) If no | | | | | forwarding policies | | | | | exist, the highest | | | | | priority of existing | | | | | forwarding policies will | | | | | set to 1 by default. | | | | | | | | | | This parameter is | | | | | unsupported.

If it is | | | | passed, an error will be returned. | | | | | | | | For dedicated load balancers, this | | | | parameter will take effect only when | | | | advanced forwarding is enabled | | | | (**enhance_l7policy_enable** is set | | | | to **true**). If it is passed when | | | | **enhance_l7policy_enable** is set to | | | | **false**, an error will be returned. | | | | | | | | Format: | | | | *protocol://host:port/path?query* | | | | | | | | At least one of the four parameters | | | | (**protocol**, **host**, **port**, | | | | and **path**) must be passed, or | | | | their values cannot be set to | | | | **${xxx}** at the same time. | | | | (**${xxx}** indicates that the value | | | | in the request will be inherited. For | | | | example, **${host}** indicates the | | | | host in the URL to be redirected.) | | | | | | | | The values of **protocol** and | | | | **port** cannot be the same as those | | | | of the associated listener, and | | | | either **host** or **path** must be | | | | passed or their values cannot be | | | | **${xxx}** at the same time. | | | | | | | | This parameter is unsupported.

This | | | object | parameter will take effect when | | | | **enhance_l7policy_enable** is set to | | | | **true**. If this parameter is passed | | | | and **enhance_l7policy_enable** is | | | | set to **false**, an error will be | | | | returned. For shared load balancers, | | | | this parameter is not supported. If | | | | it is passed, an error will be | | | | returned. | | | | | | | | This parameter is unsupported. Please | | | | do not use it. | +---------------------------------------+---------------------------------------+---------------------------------------+ | priority | Integer | Specifies the forwarding policy | | | | priority. This parameter is available | | | | only for dedicated load balancers and | | | | will take effect when | | | | **enhance_l7policy_enable** is set to | | | | **true**. | | | | | | | | A smaller value indicates a higher | | | | priority. The value must be unique | | | | for each forwarding policy of the | | | | same listener. | | | | | | | | If **action** is set to | | | | **REDIRECT_TO_LISTENER**, the value | | | | can only be **0**, indicating that | | | | **REDIRECT_TO_LISTENER** has the | | | | highest priority. | | | | | | | | - If **enhance_l7policy_enable** is | | | | set to **false**, forwarding | | | | policies are automatically | | | | prioritized based on the original | | | | sorting logic. Forwarding policy | | | | priorities are independent of each | | | | other regardless of domain names. | | | | If forwarding policies use the | | | | same domain name, their priorities | | | | follow the order of exact match | | | | (**EQUAL_TO**), prefix match | | | | (**STARTS_WITH**), and regular | | | | expression match (**REGEX**). If | | | | prefix match is used for matching, | | | | the longer the path, the higher | | | | the priority. If a forwarding | | | | policy contains only a domain name | | | | without a path specified, the path | | | | is **/**, and prefix match is used | | | | by default. | | | | | | | | - If **enhance_l7policy_enable** is | | | | set to **true** and this parameter | | | | is not passed, the priority will | | | | set to a sum of 1 and the highest | | | | priority of existing forwarding | | | | policy in the same listener by | | | | default. There will be two cases: | | | | a) If the highest priority of | | | | existing forwarding policies is | | | | the maximum (10,000), the | | | | forwarding policy will fail to | | | | create because the final priority | | | | for creating the forwarding policy | | | | is the sum of 1 and 10,000, which | | | | exceeds the maximum. In this case, | | | | please specify a value or adjust | | | | the priorities of existing | | | | forwarding policies. b) If no | | | | forwarding policies exist, the | | | | highest priority of existing | | | | forwarding policies will set to 1 | | | | by default. | | | | | | | | This parameter is unsupported.
