result: LoadBalancer { id, adaptive_routing, country_pools, 20 more }
id: optional string
adaptive_routing: optional AdaptiveRouting { failover_across_pools }

Controls features that modify the routing of requests to pools and origins in response to dynamic conditions, such as during the interval between active health monitoring requests. For example, zero-downtime failover occurs immediately when an origin becomes unavailable due to HTTP 521, 522, or 523 response codes. If there is another healthy origin in the same pool, the request is retried once against this alternate origin.

failover_across_pools: optional boolean

Extends zero-downtime failover of requests to healthy origins from alternate pools, when no healthy alternate exists in the same pool, according to the failover order defined by traffic and origin steering. When set false (the default) zero-downtime failover will only occur between origins within the same pool. See session_affinity_attributes for control over when sessions are broken or reassigned.

country_pools: optional map[array of string]

A mapping of country codes to a list of pool IDs (ordered by their failover priority) for the given country. Any country not explicitly defined will fall back to using the corresponding region_pool mapping if it exists else to default_pools.

created_on: optional string
default_pools: optional array of DefaultPools

A list of pool IDs ordered by their failover priority. Pools defined here are used by default, or when region_pools are not configured for a given region.

Determines the authoritative location when ECS is not preferred, does not exist in the request, or its GeoIP lookup is unsuccessful.

  • "pop": Use the Cloudflare PoP location.

session_affinity: optional SessionAffinity

Specifies the type of session affinity the load balancer should use unless specified as "none". The supported types are: - "cookie": On the first request to a proxied load balancer, a cookie is generated, encoding information of which origin the request will be forwarded to. Subsequent requests, by the same client to the same load balancer, will be sent to the origin server the cookie encodes, for the duration of the cookie and as long as the origin server remains healthy. If the cookie has expired or the origin server is unhealthy, then a new origin server is calculated and used. - "ip_cookie": Behaves the same as "cookie" except the initial origin selection is stable and based on the client's ip address. - "header": On the first request to a proxied load balancer, a session key based on the configured HTTP headers (see session_affinity_attributes.headers) is generated, encoding the request headers used for storing in the load balancer session state which origin the request will be forwarded to. Subsequent requests to the load balancer with the same headers will be sent to the same origin server, for the duration of the session and as long as the origin server remains healthy. If the session has been idle for the duration of session_affinity_ttl seconds or the origin server is unhealthy, then a new origin server is calculated and used. See headers in session_affinity_attributes for additional required configuration.

One of the following:
"none"
"cookie"
"ip_cookie"
"header"
session_affinity_attributes: optional SessionAffinityAttributes { drain_duration, headers, require_all_headers, 3 more }

Configures attributes for session affinity.

drain_duration: optional number

Configures the drain duration in seconds. This field is only used when session affinity is enabled on the load balancer.

headers: optional array of string

Configures the names of HTTP headers to base session affinity on when header session_affinity is enabled. At least one HTTP header name must be provided. To specify the exact cookies to be used, include an item in the following format: "cookie:<cookie-name-1>,<cookie-name-2>" (example) where everything after the colon is a comma-separated list of cookie names. Providing only "cookie" will result in all cookies being used. The default max number of HTTP header names that can be provided depends on your plan: 5 for Enterprise, 1 for all other plans.

require_all_headers: optional boolean

When header session_affinity is enabled, this option can be used to specify how HTTP headers on load balancing requests will be used. The supported values are: - "true": Load balancing requests must contain all of the HTTP headers specified by the headers session affinity attribute, otherwise sessions aren't created. - "false": Load balancing requests must contain at least one of the HTTP headers specified by the headers session affinity attribute, otherwise sessions aren't created.

samesite: optional "Auto" or "Lax" or "None" or "Strict"

Configures the SameSite attribute on session affinity cookie. Value "Auto" will be translated to "Lax" or "None" depending if Always Use HTTPS is enabled. Note: when using value "None", the secure attribute can not be set to "Never".

One of the following:
"Auto"
"Lax"
"None"
"Strict"
secure: optional "Auto" or "Always" or "Never"

Configures the Secure attribute on session affinity cookie. Value "Always" indicates the Secure attribute will be set in the Set-Cookie header, "Never" indicates the Secure attribute will not be set, and "Auto" will set the Secure attribute depending if Always Use HTTPS is enabled.

One of the following:
"Auto"
"Always"
"Never"
zero_downtime_failover: optional "none" or "temporary" or "sticky"

Configures the zero-downtime failover between origins within a pool when session affinity is enabled. This feature is currently incompatible with Argo, Tiered Cache, and Bandwidth Alliance. The supported values are: - "none": No failover takes place for sessions pinned to the origin (default). - "temporary": Traffic will be sent to another other healthy origin until the originally pinned origin is available; note that this can potentially result in heavy origin flapping. - "sticky": The session affinity cookie is updated and subsequent requests are sent to the new origin. Note: Zero-downtime failover with sticky sessions is currently not supported for session affinity by header.

One of the following:
"none"
"temporary"
"sticky"
session_affinity_ttl: optional number

Time, in seconds, until a client's session expires after being created. Once the expiry time has been reached, subsequent requests may get sent to a different origin server. The accepted ranges per session_affinity policy are: - "cookie" / "ip_cookie": The current default of 23 hours will be used unless explicitly set. The accepted range of values is between [1800, 604800]. - "header": The current default of 1800 seconds will be used unless explicitly set. The accepted range of values is between [30, 3600]. Note: With session affinity by header, sessions only expire after they haven't been used for the number of seconds specified.

steering_policy: optional SteeringPolicy

Steering Policy for this load balancer.

  • "off": Use default_pools.
  • "geo": Use region_pools/country_pools/pop_pools. For non-proxied requests, the country for country_pools is determined by location_strategy.
  • "random": Select a pool randomly.
  • "dynamic_latency": Use round trip time to select the closest pool in default_pools (requires pool health checks).
  • "proximity": Use the pools' latitude and longitude to select the closest pool using the Cloudflare PoP location for proxied requests or the location determined by location_strategy for non-proxied requests.
  • "least_outstanding_requests": Select a pool by taking into consideration random_steering weights, as well as each pool's number of outstanding requests. Pools with more pending requests are weighted proportionately less relative to others.
  • "least_connections": Select a pool by taking into consideration random_steering weights, as well as each pool's number of open connections. Pools with more open connections are weighted proportionately less relative to others. Supported for HTTP/1 and HTTP/2 connections.
