Overview

Note:

When making an API call, you may pass CachePolicyConfig data as a hash:

{
  comment: "string",
  name: "string", # required
  default_ttl: 1,
  max_ttl: 1,
  min_ttl: 1, # required
  parameters_in_cache_key_and_forwarded_to_origin: {
    enable_accept_encoding_gzip: false, # required
    enable_accept_encoding_brotli: false,
    headers_config: { # required
      header_behavior: "none", # required, accepts none, whitelist
      headers: {
        quantity: 1, # required
        items: ["string"],
      },
    },
    cookies_config: { # required
      cookie_behavior: "none", # required, accepts none, whitelist, allExcept, all
      cookies: {
        quantity: 1, # required
        items: ["string"],
      },
    },
    query_strings_config: { # required
      query_string_behavior: "none", # required, accepts none, whitelist, allExcept, all
      query_strings: {
        quantity: 1, # required
        items: ["string"],
      },
    },
  },
}

A cache policy configuration.

This configuration determines the following:

  • The values that CloudFront includes in the cache key. These values can include HTTP headers, cookies, and URL query strings. CloudFront uses the cache key to find an object in its cache that it can return to the viewer.

  • The default, minimum, and maximum time to live (TTL) values that you want objects to stay in the CloudFront cache.

The headers, cookies, and query strings that are included in the cache key are automatically included in requests that CloudFront sends to the origin. CloudFront sends a request when it can’t find a valid object in its cache that matches the request’s cache key. If you want to send values to the origin but not include them in the cache key, use ‘OriginRequestPolicy`.

  :max_ttl,
  :min_ttl,
  :parameters_in_cache_key_and_forwarded_to_origin)
  SENSITIVE = []
  include Aws::Structure
end

#default_ttl ⇒ Integer

The default amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value as the object’s time to live (TTL) only when the origin does not send ‘Cache-Control` or `Expires` headers with the object. For more information, see [Managing How Long Content Stays in an Edge Cache (Expiration)] in the *Amazon CloudFront Developer Guide*.

The default value for this field is 86400 seconds (one day). If the value of ‘MinTTL` is more than 86400 seconds, then the default value for this field is the same as the value of `MinTTL`.

end

#max_ttl ⇒ Integer

The maximum amount of time, in seconds, that objects stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value only when the origin sends ‘Cache-Control` or `Expires` headers with the object. For more information, see [Managing How Long Content Stays in an Edge Cache (Expiration)] in the *Amazon CloudFront Developer Guide*.

The default value for this field is 31536000 seconds (one year). If the value of ‘MinTTL` or `DefaultTTL` is more than 31536000 seconds, then the default value for this field is the same as the value of `DefaultTTL`.
