Remarks

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 headers, cookies, and query strings that are included in the cache key are also included in requests that CloudFront sends to the origin. CloudFront sends a request when it can't find an 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 .

Synopsis

Constructors

ParametersInCacheKeyAndForwardedToOriginProperty()

This object determines the values that CloudFront includes in the cache key.

Properties

CookiesConfig	An object that determines whether any cookies in viewer requests (and if so, which cookies) are included in the cache key and in requests that CloudFront sends to the origin.
EnableAcceptEncodingBrotli	A flag that can affect whether the `Accept-Encoding` HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.
EnableAcceptEncodingGzip	A flag that can affect whether the `Accept-Encoding` HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.
HeadersConfig	An object that determines whether any HTTP headers (and if so, which headers) are included in the cache key and in requests that CloudFront sends to the origin.
QueryStringsConfig	An object that determines whether any URL query strings in viewer requests (and if so, which query strings) are included in the cache key and in requests that CloudFront sends to the origin.

Constructors

ParametersInCacheKeyAndForwardedToOriginProperty()

This object determines the values that CloudFront includes in the cache key.

public ParametersInCacheKeyAndForwardedToOriginProperty()

Remarks

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.

Properties

CookiesConfig

An object that determines whether any cookies in viewer requests (and if so, which cookies) are included in the cache key and in requests that CloudFront sends to the origin.

public object CookiesConfig { get; set; }

Property Value

object

Remarks

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-cachepolicy-parametersincachekeyandforwardedtoorigin.html#cfn-cloudfront-cachepolicy-parametersincachekeyandforwardedtoorigin-cookiesconfig

Type union: either IResolvable or CfnCachePolicy.ICookiesConfigProperty

EnableAcceptEncodingBrotli

A flag that can affect whether the Accept-Encoding HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.

public object? EnableAcceptEncodingBrotli { get; set; }

Property Value

object

Remarks

This field is related to the EnableAcceptEncodingGzip field. If one or both of these fields is true and the viewer request includes the Accept-Encoding header, then CloudFront does the following:

For more information, see Compression support in the Amazon CloudFront Developer Guide .

If you set this value to true , and this cache behavior also has an origin request policy attached, do not include the Accept-Encoding header in the origin request policy. CloudFront always includes the Accept-Encoding header in origin requests when the value of this field is true , so including this header in an origin request policy has no effect.

If both of these fields are false , then CloudFront treats the Accept-Encoding header the same as any other HTTP header in the viewer request. By default, it's not included in the cache key and it's not included in origin requests. In this case, you can manually add Accept-Encoding to the headers whitelist like any other HTTP header.

Type union: either bool or IResolvable

EnableAcceptEncodingGzip

A flag that can affect whether the Accept-Encoding HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.

public object EnableAcceptEncodingGzip { get; set; }

Property Value

Remarks
