#cache_modeString

  • (String)

def cache_mode
  @cache_mode
end

#client_ttlFixnum

Specifies a separate client (e.g. browser client) TTL, separate from the TTL for Cloud CDN's edge caches. Leaving this empty will use the same cache TTL for both Cloud CDN and the client-facing response. The maximum allowed value is 86400s (1 day). Corresponds to the JSON property clientTtl

Returns:

  • (Fixnum)

def client_ttl
  @client_ttl
end

#default_ttlFixnum

Specifies the default TTL for cached content served by this origin for responses that do not have an existing valid TTL (max-age or s-max-age). Setting a TTL of "0" means "always revalidate" and a value of "-1" disables caching for that status code. The value of defaultTTL cannot be set to a value greater than that of maxTTL, but can be equal. 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), noting that infrequently accessed objects may be evicted from the cache before the defined TTL. Corresponds to the JSON property defaultTtl

Returns:

  • (Fixnum)

  @default_ttl
end

#max_ttlFixnum

Specifies the maximum allowed TTL for cached content served by this origin. 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. Setting a TTL of "0" means "always revalidate" and a value of "-1" disables caching for that status code. The maximum allowed value is 31,622, 400s (1 year), noting that infrequently accessed objects may be evicted from the cache before the defined TTL. Corresponds to the JSON property maxTtl

Returns:

  • (Fixnum)

#negative_cachingBoolean Also known as: negative_caching?

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. By default, Cloud CDN will apply the following default TTLs to these status codes: HTTP 300 (Multiple Choice), 301, 308 (Permanent Redirects): 10m HTTP 404 (Not Found), 410 (Gone), 451 (Unavailable For Legal Reasons): 120s HTTP 405 (Method Not Found), 414 (URI Too Long), 501 (Not Implemented): 60s These defaults can be overridden in negative_caching_policy Corresponds to the JSON property negativeCaching

Returns:

  • (Boolean)

#negative_caching_policyArray<Google::Apis::ComputeAlpha::BackendBucketCdnPolicyNegativeCachingPolicy>

Sets a cache TTL for the specified HTTP status code. negative_caching must be enabled to configure negative_caching_policy. Omitting the policy and leaving negative_caching enabled will use Cloud CDN's default cache TTLs. Note that when specifying an explicit negative_caching_policy, you should take care to specify a cache TTL for all response codes that you wish to cache. Cloud CDN will not apply any default negative caching when a policy exists. Corresponds to the JSON property negativeCachingPolicy

#request_coalescingBoolean Also known as: request_coalescing?

If true then Cloud CDN will combine multiple concurrent cache fill requests into a small number of requests to the origin. Corresponds to the JSON property requestCoalescing

Returns:

  • (Boolean)

end

#signed_url_cache_max_age_secFixnum

Maximum number of seconds the response to a signed URL request will be considered fresh. After this time period, the response will be revalidated before being served. Defaults to 1hr (3600s). When serving responses to signed URL requests, Cloud CDN will internally behave as though all responses from this backend had a "Cache-Control: public, max-age=[TTL]" header, regardless of any existing Cache-Control header. The actual headers served in responses will not be altered. Corresponds to the JSON property signedUrlCacheMaxAgeSec

Returns:

  • (Fixnum)
