Cache policy and matching configuration.

Fields

header: HeaderName

Header that carries the idempotency key.

methods: Vec<Method>

Methods to protect. Default: [POST].

ttl_secs: u64

Time-to-live for cached results (seconds). Default: 86400 (24h).

scope: Scope

Include method+path in the cache key. Default: MethodAndPath.

coalesce_inflight: bool

If true, concurrent calls with same key wait for the first to finish. Default: true.

inflight_wait_timeout_ms: Option<u64>

Optional timeout for waiting on in-flight (milliseconds). Default: None (wait indefinitely).

max_cached_body_bytes: usize

Maximum response body size to cache (bytes). Default: 1 MiB.

max_request_body_bytes: usize

Maximum request body size to hash (bytes). Requests exceeding this are rejected with 413.

verify_payload: bool

If true, enforce identical payload for the same key; otherwise only the key is checked.

cache_error_statuses: bool

If true, also cache non-success statuses. Default: true.
