Documentation
data ResponseHeadersPolicyServerTimingHeadersConfig Source #
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.
See: newResponseHeadersPolicyServerTimingHeadersConfig
smart constructor.

Create a value of ResponseHeadersPolicyServerTimingHeadersConfig
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:samplingRate:ResponseHeadersPolicyServerTimingHeadersConfig'
, responseHeadersPolicyServerTimingHeadersConfig_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.
$sel:enabled:ResponseHeadersPolicyServerTimingHeadersConfig'
, responseHeadersPolicyServerTimingHeadersConfig_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.
responseHeadersPolicyServerTimingHeadersConfig_samplingRate :: Lens' ResponseHeadersPolicyServerTimingHeadersConfig (Maybe Double) Source #
