@Generated("software.amazon.awssdk:codegen") public final class ResponseHeadersPolicyServerTimingHeadersConfig extends Object implements SdkPojo, Serializable, ToCopyableBuilder<ResponseHeadersPolicyServerTimingHeadersConfig.Builder,ResponseHeadersPolicyServerTimingHeadersConfig>

A configuration for enabling the Server-Timing header in HTTP responses sent from CloudFront. CloudFront adds this header to HTTP responses that it sends in response to requests that match a cache behavior that's associated with this response headers policy.

You can use the Server-Timing header to view metrics that can help you gain insights about the behavior and performance of CloudFront. For example, you can see which cache layer served a cache hit, or the first byte latency from the origin when there was a cache miss. You can use the metrics in the Server-Timing header to troubleshoot issues or test the efficiency of your CloudFront configuration. For more information, see Server-Timing header in the Amazon CloudFront Developer Guide.

  • Method Details

    • enabled

      public final Boolean enabled()

      A Boolean that determines whether CloudFront adds the Server-Timing header to HTTP responses that it sends in response to requests that match a cache behavior that's associated with this response headers policy.

      Returns:
      A Boolean that determines whether CloudFront adds the Server-Timing header to HTTP responses that it sends in response to requests that match a cache behavior that's associated with this response headers policy.

    • samplingRate

      public final Double samplingRate()

      A number 0–100 (inclusive) that specifies the percentage of responses that you want CloudFront to add the Server-Timing header to. When you set the sampling rate to 100, CloudFront adds the Server-Timing header to the HTTP response for every request that matches the cache behavior that this response headers policy is attached to. When you set it to 50, CloudFront adds the header to 50% of the responses for requests that match the cache behavior. You can set the sampling rate to any number 0–100 with up to four decimal places.

      Returns:
      A number 0–100 (inclusive) that specifies the percentage of responses that you want CloudFront to add the Server-Timing header to.

    • toBuilder

      public ResponseHeadersPolicyServerTimingHeadersConfig.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<ResponseHeadersPolicyServerTimingHeadersConfig.Builder,ResponseHeadersPolicyServerTimingHeadersConfig>
      Returns:
      a builder for type T

    • builder

      public static ResponseHeadersPolicyServerTimingHeadersConfig.Builder builder()

    • serializableBuilderClass

      public static Class<? extends ResponseHeadersPolicyServerTimingHeadersConfig.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
