When passing CacheSettings as input to an Aws::Client method, you can use a vanilla Hash:

{
  default_ttl: 1,
  minimum_ttl: 1,
  maximum_ttl: 1,
  allowed_http_methods: "NonEmptyString",
  cached_http_methods: "NonEmptyString",
  forwarded_cookies: {
    option: "none",     cookies_allow_list: ["string"],
  },
  forwarded_headers: {
    option: "none",     headers_allow_list: ["Accept"],   },
  forwarded_query_strings: {
    option: false,
    query_strings_allow_list: ["string"],
  },
}

Describes the cache settings of an Amazon Lightsail content delivery network (CDN) distribution.

These settings apply only to your distribution's cacheBehaviors (including the defaultCacheBehavior) that have a behavior of cache.

Returned by:

• Aws::Lightsail::Types::CreateDistributionRequest#cache_behavior_settings
• LightsailDistribution#cache_behavior_settings
• UpdateDistributionRequest#cache_behavior_settings

• #allowed_http_methods ⇒ String

  The HTTP methods that are processed and forwarded to the distribution\'s origin.

• #cached_http_methods ⇒ String

  The HTTP method responses that are cached by your distribution.

• #default_ttl ⇒ Integer

  The default amount of time that objects stay in the distribution\'s cache before the distribution forwards another request to the origin to determine whether the content has been updated.

• #forwarded_cookies ⇒ Types::CookieObject

  An object that describes the cookies that are forwarded to the origin.

• #forwarded_headers ⇒ Types::HeaderObject

  An object that describes the headers that are forwarded to the origin.

• #forwarded_query_strings ⇒ Types::QueryStringObject

  An object that describes the query strings that are forwarded to the origin.

• #maximum_ttl ⇒ Integer

  The maximum amount of time that objects stay in the distribution\'s cache before the distribution forwards another request to the origin to determine whether the object has been updated.

• #minimum_ttl ⇒ Integer

  The minimum amount of time that objects stay in the distribution\'s cache before the distribution forwards another request to the origin to determine whether the object has been updated.

The HTTP methods that are processed and forwarded to the distribution\'s origin.

You can specify the following options:

• GET,HEAD - The distribution forwards the GET and HEAD methods.

• GET,HEAD,OPTIONS - The distribution forwards the GET, HEAD, and OPTIONS methods.

• GET,HEAD,OPTIONS,PUT,PATCH,POST,DELETE - The distribution forwards the GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE methods.

If you specify the third option, you might need to restrict access to your distribution\'s origin so users can\'t perform operations that you don\'t want them to. For example, you might not want users to have permission to delete objects from your origin.

The HTTP method responses that are cached by your distribution.

You can specify the following options:

• GET,HEAD - The distribution caches responses to the GET and HEAD methods.

• GET,HEAD,OPTIONS - The distribution caches responses to the GET, HEAD, and OPTIONS methods.

The default amount of time that objects stay in the distribution\'s cache before the distribution forwards another request to the origin to determine whether the content has been updated.

The value specified applies only when the origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

An object that describes the cookies that are forwarded to the origin. Your content is cached based on the cookies that are forwarded.

An object that describes the headers that are forwarded to the origin. Your content is cached based on the headers that are forwarded.

An object that describes the query strings that are forwarded to the origin. Your content is cached based on the query strings that are forwarded.

The maximum amount of time that objects stay in the distribution\'s cache before the distribution forwards another request to the origin to determine whether the object has been updated.

The value specified applies only when the origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

The minimum amount of time that objects stay in the distribution\'s cache before the distribution forwards another request to the origin to determine whether the object has been updated.

A value of 0 must be specified for minimumTTL if the distribution is configured to forward all headers to the origin.
