RuleCondition

Information about a condition for a rule.

Each rule can optionally include up to one of each of the following conditions: http-request-method, host-header, path-pattern, and source-ip. Each rule can also optionally include one or more of each of the following conditions: http-header and query-string. Note that the value for a condition can't be empty.

For Network Load Balancer listener rules, the only supported condition is source-ip. Use SourceIpConfig with IpAddressType to match on the IP address type of the source traffic (ipv4 or ipv6).

For more information, see Quotas for your Application Load Balancers.
