PRIORITY

The priority of the rule to add. Rules are evaluated in order from highest priority to lowest priority where 0 is the highest priority and 2147483647 is the lowest priority.

--action=ACTION

The action to take if the request matches the match condition. ACTION must be one of:

allow

Allows the request from HTTP(S) Load Balancing.

deny

Denies the request from TCP/SSL Proxy and Network Load Balancing.

deny-403

Denies the request from HTTP(S) Load Balancing, with an HTTP response status code of 403.

deny-404

Denies the request from HTTP(S) Load Balancing, with an HTTP response status code of 404.

deny-502

Denies the request from HTTP(S) Load Balancing, with an HTTP response status code of 502.

fairshare

When traffic reaches the threshold limit, requests from the clients matching this rule begin to be rate-limited using the Fair Share algorithm.

rate-based-ban

Enforces rate-based ban action from HTTP(S) Load Balancing, based on rate limit options.

redirect

Redirects the request from HTTP(S) Load Balancing, based on redirect options.

redirect-to-recaptcha

(DEPRECATED) Redirects the request from HTTP(S) Load Balancing, for reCAPTCHA Enterprise assessment. This flag choice is deprecated. Use --action=redirect and --redirect-type=google-recaptcha instead.

throttle

Enforces throttle action from HTTP(S) Load Balancing, based on rate limit options.

--ban-duration-sec=BAN_DURATION_SEC

--ban-threshold-count=BAN_THRESHOLD_COUNT

Number of HTTP(S) requests for calculating the threshold for banning requests. Can only be specified if the action for the rule is rate-based-ban.

--ban-threshold-interval-sec=BAN_THRESHOLD_INTERVAL_SEC

Interval over which the threshold for banning requests is computed. Can only be specified if the action for the rule is rate-based-ban. If specified, the key will be banned for the configured BAN_DURATION_SEC when the number of requests that exceed the RATE_LIMIT_THRESHOLD_COUNT also exceed this BAN_THRESHOLD_COUNT.

--conform-action=CONFORM_ACTION

Action to take when requests are under the given threshold. When requests are throttled, this is also the action for all requests which are not dropped. CONFORM_ACTION must be (only one value is supported): allow.

--description=DESCRIPTION

An optional, textual description for the rule.

--enforce-on-key=ENFORCE_ON_KEY

Different key types available to enforce the rate limit threshold limit on:

• ip: each client IP address has this limit enforced separately
• all: a single limit is applied to all requests matching this rule
• http-header: key type takes the value of the HTTP header configured in enforce-on-key-name as the key value
• xff-ip: takes the original IP address specified in the X-Forwarded-For header as the key
• http-cookie: key type takes the value of the HTTP cookie configured in enforce-on-key-name as the key value
• http-path: key type takes the value of the URL path in the request
• sni: key type takes the value of the server name indication from the TLS session of the HTTPS request
• region-code: key type takes the value of the region code from which the request originates
• tls-ja3-fingerprint: key type takes the value of JA3 TLS/SSL fingerprint if the client connects using HTTPS, HTTP/2 or HTTP/3
• user-ip: key type takes the IP address of the originating client, which is resolved based on user-ip-request-headers configured with the security policy

ENFORCE_ON_KEY must be one of: ip, all, http-header, xff-ip, http-cookie, http-path, sni, region-code, tls-ja3-fingerprint, user-ip.

--enforce-on-key-configs=[[all],[ip],[xff-ip],[http-cookie=HTTP_COOKIE],[http-header=HTTP_HEADER],[http-path],[sni],[region-code],[tls-ja3-fingerprint],[user-ip]],[…]

--exceed-action=EXCEED_ACTION
