// and see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html)
// . With the latest version, AWS WAF has a single set of endpoints for regional
// and global use. Gets detailed information about a specified number of
// requests--a sample--that AWS WAF randomly selects from among the first 5,000
// requests that your AWS resource received during a time range that you choose.
// You can specify a sample size of up to 500 requests, and you can specify any
// time range in the previous three hours. GetSampledRequests returns a time
// range, which is usually the time range that you specified. However, if your
// resource (such as a CloudFront distribution) received 5,000 requests before the
// specified time range elapsed, GetSampledRequests returns an updated time range.
// This new time range indicates the actual period during which AWS WAF selected
// the requests in the sample.
