    Describes the request headers that a Lightsail distribution bases caching on.

    For the headers that you specify, your distribution caches separate versions of the specified content based on the header values in viewer requests. For example, suppose viewer requests for logo.jpg contain a custom product header that has a value of either acme or apex, and you configure your distribution to cache your content based on values in the product header. Your distribution forwards the product header to the origin and caches the response from the origin once for each header value.

    • Method Detail

      • option

        public final ForwardValues option()

        The headers that you want your distribution to forward to your origin and base caching on.

        You can configure your distribution to do one of the following:

        • all - Forward all headers to your origin.

        • none - Forward only the default headers.

        • allow-list - Forward only the headers you specify using the headersAllowList parameter.

        If the service returns an enum value that is not available in the current SDK version, option will return ForwardValues.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from optionAsString().

        Returns:
        The headers that you want your distribution to forward to your origin and base caching on.

        You can configure your distribution to do one of the following:

        • all - Forward all headers to your origin.

        • none - Forward only the default headers.

        • allow-list - Forward only the headers you specify using the headersAllowList parameter.

        ForwardValues

      • optionAsString

        public final String optionAsString()

        The headers that you want your distribution to forward to your origin and base caching on.

        You can configure your distribution to do one of the following:

        • all - Forward all headers to your origin.

        • none - Forward only the default headers.

        • allow-list - Forward only the headers you specify using the headersAllowList parameter.

        If the service returns an enum value that is not available in the current SDK version, option will return ForwardValues.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from optionAsString().

        Returns:
        The headers that you want your distribution to forward to your origin and base caching on.

        You can configure your distribution to do one of the following:

        • all - Forward all headers to your origin.

        • none - Forward only the default headers.

        • allow-list - Forward only the headers you specify using the headersAllowList parameter.

      • headersAllowList

        public final List<HeaderEnum> headersAllowList()

        The specific headers to forward to your distribution's origin.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasHeadersAllowList() method.

        Returns:
        The specific headers to forward to your distribution's origin.

      • hasHeadersAllowList

        public final boolean hasHeadersAllowList()
        For responses, this returns true if the service returned a value for the HeadersAllowList property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • headersAllowListAsStrings

        public final List<String> headersAllowListAsStrings()

        The specific headers to forward to your distribution's origin.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasHeadersAllowList() method.

        Returns:
        The specific headers to forward to your distribution's origin.
