Name	Description	Type	Notes
_create_time	Timestamp of resource creation	EpochMsTimestamp	Readonly Sortable
_create_user	ID of the user who created this resource	string	Readonly
_last_modified_time	Timestamp of last modification	EpochMsTimestamp	Readonly Sortable
_last_modified_user	ID of the user who last modified this resource	string	Readonly
_links	References related to this resource The server will populate this field when returing the resource. Ignored on PUT and POST.	array of ResourceLink	Readonly
_protection	Indicates protection status of this resource Protection status is one of the following: PROTECTED - the client who retrieved the entity is not allowed to modify it. NOT_PROTECTED - the client who retrieved the entity is allowed to modify it REQUIRE_OVERRIDE - the client who retrieved the entity is a super user and can modify it, but only when providing the request header X-Allow-Overwrite=true. UNKNOWN - the _protection field could not be determined for this entity.	string	Readonly
_revision	Generation of this resource config The _revision property describes the current revision of the resource. To prevent clients from overwriting each other's changes, PUT operations must include the current _revision of the resource, which clients should obtain by issuing a GET operation. If the _revision provided in a PUT request is missing or stale, the operation will be rejected.	int
_schema	Schema for this resource	string	Readonly
_self	Link to this resource	SelfResourceLink	Readonly
_system_owned	Indicates system owned resource	boolean	Readonly
actions	Actions to be executed A list of actions to be executed at specified phase when load balancer rule matches. The actions are used to manipulate application traffic, such as rewrite URI of HTTP messages, redirect HTTP messages, etc.	array of LbRuleAction (Abstract type: pass one of the following concrete types) LbConnectionDropAction LbHttpRedirectAction LbHttpRejectAction LbHttpRequestHeaderDeleteAction LbHttpRequestHeaderRewriteAction LbHttpRequestUriRewriteAction LbHttpResponseHeaderDeleteAction LbHttpResponseHeaderRewriteAction LbJwtAuthAction LbSelectPoolAction LbSslModeSelectionAction LbVariableAssignmentAction LbVariablePersistenceLearnAction LbVariablePersistenceOnAction	Required Maximum items: 60
description	Description of this resource	string	Maximum length: 1024 Sortable
display_name	Identifier to use when displaying entity in logs or GUI Defaults to ID if not set	string	Maximum length: 255 Sortable
id	Unique identifier of this resource	string	Sortable
match_conditions	Conditions to match application traffic A list of match conditions used to match application traffic. Multiple match conditions can be specified in one load balancer rule, each match condition defines a criterion to match application traffic. If no match conditions are specified, then the load balancer rule will always match and it is used typically to define default rules. If more than one match condition is specified, then match strategy determines if all conditions should match or any one condition should match for the load balancer rule to considered a match.	array of LbRuleCondition (Abstract type: pass one of the following concrete types) LbHttpRequestBodyCondition LbHttpRequestCookieCondition LbHttpRequestHeaderCondition LbHttpRequestMethodCondition LbHttpRequestUriArgumentsCondition LbHttpRequestUriCondition LbHttpRequestVersionCondition LbHttpResponseHeaderCondition LbHttpSslCondition LbIpHeaderCondition LbSslSniCondition LbTcpHeaderCondition LbVariableCondition	Maximum items: 60
match_strategy	Strategy to match multiple conditions Strategy to define how load balancer rule is considered a match when multiple match conditions are specified in one rule. If match_stragety is set to ALL, then load balancer rule is considered a match only if all the conditions match. If match_strategy is set to ANY, then load balancer rule is considered a match if any one of the conditions match.	string	Required Enum: ALL, ANY
phase	Load balancer processing phase Each load balancer rule is used at a specific phase of load balancer processing. Currently five phases are supported, HTTP_REQUEST_REWRITE, HTTP_FORWARDING, HTTP_RESPONSE_REWRITE, HTTP_ACCESS and TRANSPORT. When an HTTP request message is received by load balancer, all HTTP_REQUEST_REWRITE rules, if present are executed in the order they are applied to virtual server. And then if HTTP_FORWARDING rules present, only first matching rule's action is executed, remaining rules are not checked. HTTP_FORWARDING rules can have only one action. If the request is forwarded to a backend server and the response goes back to load balancer, all HTTP_RESPONSE_REWRITE rules, if present, are executed in the order they are applied to the virtual server. In HTTP_ACCESS phase, user can define action to control access using JWT authentication. In TRANSPORT phase, user can define the condition to match SNI in TLS client hello and define the action to do SSL end-to-end, SSL offloading or SSL passthrough using a specific load balancer server pool.	string	Required Enum: HTTP_REQUEST_REWRITE, HTTP_FORWARDING, HTTP_RESPONSE_REWRITE, HTTP_ACCESS, TRANSPORT
resource_type	Must be set to the value LbRule	string
tags	Opaque identifiers meaningful to the API user	array of Tag	Maximum items: 30
