#client_ttl ⇒ ::Google::Cloud::Compute::V1::Duration

Returns Specifies a separate client (e.g. browser client) maximum TTL for cached content. This is used to clamp the max-age (or Expires) value sent to the client. With FORCE_CACHE_ALL, the lesser of clientTtl and defaultTtl is used for the response max-age directive, along with a "public" directive. For cacheable content in CACHE_ALL_STATIC mode, clientTtl clamps the max-age from the origin (if specified), or else sets the response max-age directive to the lesser of the clientTtl and defaultTtl, and also ensures a "public" cache-control directive is present. The maximum allowed value is 31,622,400s (1 year). If not specified, Cloud CDN uses 3600s (1 hour) for CACHE_ALL_STATIC mode. Cannot exceed maxTtl. Cannot be specified when cacheMode is USE_ORIGIN_HEADERS.

#default_ttl ⇒ ::Google::Cloud::Compute::V1::Duration

Returns Specifies the default TTL for cached content for responses that do not have an existing valid TTL (max-age or s-maxage). Setting a TTL of "0" means "always revalidate". The value of defaultTtl cannot be set to a value greater than that of maxTtl. When the cacheMode is set to FORCE_CACHE_ALL, the defaultTtl will overwrite the TTL set in all responses. The maximum allowed value is 31,622,400s (1 year). Infrequently accessed objects may be evicted from the cache before the defined TTL. If not specified, Cloud CDN uses 3600s (1 hour) for CACHE_ALL_STATIC and FORCE_CACHE_ALL modes. Cannot be specified when cacheMode is USE_ORIGIN_HEADERS.

#max_ttl ⇒ ::Google::Cloud::Compute::V1::Duration

Returns Specifies the maximum allowed TTL for cached content. Cache directives that attempt to set a max-age or s-maxage higher than this, or an Expires header more than maxTtl seconds in the future will be capped at the value of maxTtl, as if it were the value of an s-maxage Cache-Control directive. Headers sent to the client will not be modified. Setting a TTL of "0" means "always revalidate". The maximum allowed value is 31,622,400s (1 year). Infrequently accessed objects may be evicted from the cache before the defined TTL. If not specified, Cloud CDN uses 86400s (1 day) for CACHE_ALL_STATIC mode.

#negative_caching ⇒ ::Boolean

Returns Negative caching allows per-status code TTLs to be set, in order to apply fine-grained caching for common errors or redirects. This can reduce the load on your origin and improve end-user experience by reducing response latency. When the cacheMode is set to CACHE_ALL_STATIC or USE_ORIGIN_HEADERS, negative caching applies to responses with the specified response code that lack any Cache-Control, Expires, or Pragma: no-cache directives. When the cacheMode is set to FORCE_CACHE_ALL, negative caching applies to all responses with the specified response code, and overrides any caching headers. By default, Cloud CDN applies the following TTLs to these HTTP status codes:

  • 300 (Multiple Choice), 301, 308 (Permanent Redirects): 10m
  • 404 (Not Found), 410 (Gone), 451 (Unavailable For Legal Reasons): 120s
  • 405 (Method Not Found), 501 (Not Implemented): 60s

These defaults can be overridden in negativeCachingPolicy. If not specified, Cloud CDN applies negative caching by default.

#serve_while_stale ⇒ ::Google::Cloud::Compute::V1::Duration

Returns Serve existing content from the cache (if available) when revalidating content with the origin, or when an error is encountered when refreshing the cache. This setting defines the default "max-stale" duration for any cached responses that do not specify a max-stale directive. Stale responses that exceed the TTL configured here will not be served. The default limit (max-stale) is 86400s (1 day), which will allow stale content to be served up to this limit beyond the max-age (or s-maxage) of a cached response. The maximum allowed value is 604800 (1 week). Set this to zero (0) to disable serve-while-stale.
