SetLoadBalancerHTTPSListenerAttribute

The name of this action.

Value: SetLoadBalancerHTTPSListenerAttribute

The frontend port used by the SLB instance.

Value range: 1 to 65535

The ID of the SLB instance.

The ID of the region to which the SLB instance belongs.

To query the region ID, refer to the list ofregions and zones or call DescribeRegions.

Optional. The ID of the access control list associated with the listener.

If the value of the AclStatus parameter is on, this parameter is required.

Optional. Indicates whether to enable access control.

Valid values: on | off

Optional. The access control method:

• white: Indicates a whitelist. Only requests from the IP addresses or CIDR blocks in the selected access control list are forwarded. It applies to scenarios where an application allows access only from specific IP addresses.

  Enabling a white access control list poses some risks to your services. After a whitelist is configured, only the IP addresses in the list can access the listener. If you enable a whitelist without adding any IP addresses to the list, all requests are forwarded.

• black: Indicates a blacklist. Requests from the IP addresses or CIDR blocks in the selected access control list are not forwarded (that is, they are blocked). It applies to scenarios where an application denies access only from specific IP addresses.

  If you enable a blacklist without adding any IP addresses to the list, all requests are forwarded.

If the value of the AclStatus parameter is on, this parameter is required.

Optional. The peak bandwidth of the listener.

Value: 1 | 1-5120

• -1: The peak bandwidth is not limited.
• 1 to 5120: The sum of the peak bandwidth values of all listeners cannot surpass the peak bandwidth of the SLB instance.

Optional. The ID of the CA certificate.

If both the CA certificate and the server certificate are uploaded, mutual authentication is established. If only the server certificate is uploaded, one-way authentication is established.

Optional. The cookie configured on the backend server.

The cookie must be 1 to 200 characters in length and can only contain ASCII English letters and numbers. It cannot contain commas (,), semicolons (;), or spaces, nor can it begin with $.

If the value of StickySession is on and the value of StickySessionType is server, this parameter is required.

Optional. Timeout period of the cookie.

Value range: 1 to 86400. Unit: seconds

Optional. A description of the listener.

Optional. Indicates whether to enable the HTTP/2 feature.

Valid values: on | off

Optional. Indicates whether to enable Gzip compression to compress a specific file type.

Valid value: on | off. Default value: off

Optional. Indicates whether to enable the health check function.

Valid values: on | off

Optional. The port used for health checks.

Value range: 1 to 65535

Optional. The domain name used for health checks. Valid values:

• $_ip: the private IP address of the backend server. If the IP address is specified or this parameter is not specified, SLB uses private IP addresses of backend servers as the domain names for health checks.
• domain: The domain name must be 1 to 80 characters in length, and can only contain letters, numbers, periods (.), and hyphens (-).

Optional. The HTTP status code indicating that the health check is normal. Separate multiple HTTP status codes by commas (,).

Valid values: http_2xx | http_3xx | http_4xx | http_5xx

Optional. The time interval between two consecutive health checks.

Value range: 1 to 50. Unit: seconds

Optional. The length of time to wait for the response from the health check. If the backend ECS instance does not send a correct response within the specified time, the health check fails.

Value range: 1 to 300. Unit: seconds

Optional. The URI used for health checks.

Optional. The number of consecutive successes of health checks before a backend server is declared as healthy (from failure to success).

Value range: 2 to 10

Optional. The idle connection timeout. Value range: 1 to 60. Default value: 15. Unit: seconds

If no request is received during the specified timeout period, SLB temporarily terminates the connection and restarts the connection when the next request is received.

Optional. The request timeout. Value range: 1 to 180. Default value: 60. Unit: seconds.

If no response is received from the backend server during the specified timeout period, SLB stops waiting and sends an HTTP 504 error to the client.

Optional. The algorithm used to distribute traffic. Valid values:

• wrr (default): Backend servers with higher weights receive more requests than those with smaller weights.
• wlc: A server with a higher weight receives more requests. When the weight values of two backend servers are the same, the server with a smaller number of connections is more likely to be polled.
• rr: Requests are evenly and sequentially distributed to backend servers.

Optional. The ID of the server certificate.

Optional. Indicates whether to enable session persistence.

Valid values: on | off

Optional. The method used to handle the cookie. Valid values:

• insert: Insert a cookie.

  SLB adds a cookie to the first response from the backend server (that is, it inserts SERVERID in the HTTP/HTTPS response packet). Then, the next request contains the cookie and the listener distributes the request to the same backend server.

• server: Rewrite the cookie.

  SLB overwrites the original cookie when a new cookie is set. The next time the client carries the new cookie to access SLB, the listener distributes the request to the previously recorded backend server.

You can only specify the TLSCipherPolicy parameter for guaranteed-performance instances. Each security policy includes the TLS protocol versions that can be selected by HTTPS and the supported cipher suites.
