ComputeBackendBucketBackendBucketCdnPolicy class

cdn_policy block — Cloud CDN configuration for this backend bucket. Only honored when GoogleComputeBackendBucket.enableCdn is true. Distinct type from BackendServiceCdnPolicy: the shape is similar but the schema has bucket-specific quirks (no cacheKeyPolicy.includeHost / includeProtocol / includeQueryString — buckets only expose the queryStringWhitelist / includeHttpHeaders axes).

Properties

bypassCacheOnRequestHeaders → List<ComputeBackendBucketBackendBucketCdnBypassCacheOnRequestHeader>?
Bypass the cache when any of these request headers is present. Up to 5 entries.
final
cacheKeyPolicy → ComputeBackendBucketBackendBucketCdnCacheKeyPolicy?
Cache key policy — which request components participate in the cache key.
final
cacheMode → BackendBucketCacheMode?
Cache mode. Defaults to CACHE_ALL_STATIC when CDN is enabled.
final
clientTtl → TfArg<int>?
Max TTL (seconds) the cache will serve content to clients for. Must be omitted when cacheMode is BackendBucketCacheMode.useOriginHeaders.
final
defaultTtl → TfArg<int>?
Default TTL for cached content with no upstream Cache-Control. Must be omitted when cacheMode is BackendBucketCacheMode.useOriginHeaders.
final
hashCode → int
The hash code for this object.
no setterinherited
maxTtl → TfArg<int>?
Hard ceiling on cached content TTL. Must be omitted when cacheMode is BackendBucketCacheMode.useOriginHeaders.
final
negativeCaching → TfArg<bool>?
Negative caching for selected status codes. Pair with negativeCachingPolicy for per-code TTLs.
final
negativeCachingPolicy → List<ComputeBackendBucketBackendBucketCdnNegativeCachingPolicy>?
Per-status-code negative-cache TTLs. Only honored when negativeCaching is true.
final
requestCoalescing → TfArg<bool>?
Coalesce concurrent cache-fill requests to the origin.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
serveWhileStale → TfArg<int>?
Serve cached content during origin revalidation or errors (seconds).
final
signedUrlCacheMaxAgeSec → TfArg<int>?
TTL for signed-URL responses (defaults to 3600 if unset).
final
