Server Load Balancer:CreateLoadBalancerHTTPListener

The ID of the region where the CLB instance is deployed.

You can query the region ID from the Regions and zones list or by calling the DescribeRegions operation.

The ID of the CLB instance.

The maximum bandwidth of the listener. Unit: Mbit/s. Valid values:

-1: specifies that the bandwidth of the listener is unlimited.

The frontend port that is used by the CLB instance.

Valid values: 1 to 65535.

The backend port that is used by the CLB instance.

Valid values: 1 to 65535.

Specifies whether to use the X-Forwarded-For header to retrieve client IP addresses. Valid values:

• on (default)
• off

The scheduling algorithm. Valid values:

• wrr (default): Backend servers with higher weights receive more requests than backend servers with lower weights.
• rr: Requests are distributed to backend servers in sequence.

Specifies whether to enable session persistence. Valid values:

• on: yes
• off (default): no

The method that is used to handle cookies. Valid values:

• insert: inserts a cookie.

  The first time a client accesses CLB, CLB inserts a cookie into the response packet. Subsequent requests from the client that carry the cookie are distributed to the same backend server as the first request.

• server: rewrites the original cookie.

  CLB rewrites the custom cookies in requests from a client. Subsequent requests from the client that carry the new cookie are forwarded to the same backend server as the first request.

The tags.

The timeout period of a cookie. Unit: seconds.

Valid values: 1 to 86400.

The cookie configured for the server.

The cookie must be 1 to 200 characters in length, and can contain only ASCII letters and digits. It cannot contain commas (,), semicolons (;), space characters, or start with a dollar sign ($).

Specifies whether to enable the health check feature. Valid values:

• on: yes
• off: no

The health check method used in HTTP health checks. Valid values: head and get.

The domain name that is used for health checks. Valid values:

• $_ip: the private IP address of a backend server. If an IP address is specified, or this parameter is not specified, the CLB instance uses the private IP address of each backend server as the domain name for health checks.
• domain: The domain name must be 1 to 80 characters in length, and can contain letters, digits, periods (.), and hyphens (-).

The URI that is used for health checks.

The URI must be 1 to 80 characters in length, and can contain letters, digits, hyphens (-), forward slashes (/), periods (.), percent signs (%), question marks (?), number signs (#), and ampersands (&). The URI must start with a forward slash (/) but cannot be a single forward slash (/).

The number of times that an unhealthy backend server must consecutively pass health checks before it is declared healthy. In this case, the health status is changed from fail to success.

Valid values: 2 to 10.

The number of times that a healthy backend server must consecutively fail health checks before it is declared unhealthy. In this case, the health status is changed from success to fail.

Valid values: 2 to 10.

The timeout period of a health check response. If a backend ECS instance does not respond within the specified timeout period, the ECS instance fails the health check. Unit: seconds

Valid values: 1 to 300.

The backend port that is used for health checks.

Valid values: 1 to 65535.

The interval between two consecutive health checks. Unit: seconds.

Valid values: 1 to 50.

The HTTP status code for a successful health check. Separate multiple HTTP status codes with commas (,).

Valid values: http_2xx (default), http_3xx, http_4xx, and http_5xx.

The ID of the vServer group.

Indicates whether the SLB-IP header is used to retrieve the virtual IP address (VIP) requested by the client. Valid values:

• on
• off (default): no

Indicates whether the SLB-ID header is used to retrieve the ID of the CLB instance. Valid values:

• on
• off (default): no

Specifies whether to use the X-Forwarded-Proto header to retrieve the listener protocol. Valid values:

• on
• off (default): no

Specifies whether to enable GZIP compression to compress specific types of files. Valid values:

• on (default)
• off

The ID of the network access control list (ACL) that is associated with the listener.

The type of access control. Valid values:

• white: Only requests from IP addresses and CIDR blocks on the whitelist are forwarded by the listener. Your service may be adversely affected if the whitelist is not properly configured. If a whitelist is configured, the listener forwards only requests from IP addresses that are added to the whitelist.

  If you configure a whitelist but do not add an IP address to the whitelist, the listener forwards all requests.

• black: Requests from the IP addresses and CIDR blocks on the blacklist are blocked.

  If you configure a blacklist but do not add an IP address to the blacklist, the listener forwards all requests.

Specifies whether to enable access control. Valid values:

• on: yes
• off (default): no

The name of the listener.

The name must be 1 to 256 characters in length, and can contain letters, digits, hyphens (-), forward slashes (/), periods (.), and underscores (_).

Specifies whether to enable HTTP-to-HTTPS redirection. Valid values:

• on: yes
• off (default): no

The listening port that is used to redirect HTTP requests to HTTPS.

The timeout period of an idle connection. Unit: seconds.

Default value: 15. Valid values: 1 to 60.

If no request is received within the specified timeout period, SLB closes the connection. When a request is received, SLB establishes a new connection.

The timeout period of a request. Unit: seconds.

Default value: 60. Valid values: 1 to 180.

If no response is received from the backend server within the specified timeout period, CLB sends an HTTP 504 error code to the client.

Specifies whether to use the XForwardedFor_SLBPORT header to retrieve the listener port of the CLB instance. Valid values:

• on
• off

Specifies whether to use the XForwardedFor_ClientSrcPort header to retrieve the client port. Valid values:

• on
• off
