// This is AWS WAF Classic documentation. For more information, see AWS WAF Classic
// (https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html)
// in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API
// 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. When you want to create, update, or delete AWS WAF objects, get a
// change token and include the change token in the create, update, or delete
// request. Change tokens ensure that your application doesn't submit conflicting
// requests to AWS WAF. Each create, update, or delete request must use a unique
// change token. If your application submits a GetChangeToken request and then
// submits a second GetChangeToken request before submitting a create, update, or
// delete request, the second GetChangeToken request returns the same value as the
// first GetChangeToken request. When you use a change token in a create, update,
// or delete request, the status of the change token changes to PENDING, which
// indicates that AWS WAF is propagating the change to all AWS WAF servers. Use
// GetChangeTokenStatus to determine the status of your change token.
