The ID of the WAF web ACL that you want to list the associated distributions. If you specify "null" for the ID, the request returns a list of the distributions that aren't associated with a web ACL.

Use <code>Marker</code> and <code>MaxItems</code> to control pagination of results. If you have more than <code>MaxItems</code> distributions that satisfy the request, the response includes a <code>NextMarker</code> element. To get the next page of results, submit another request. For the value of <code>Marker</code>, specify the value of <code>NextMarker</code> from the last response. (For the first request, omit <code>Marker</code>.)

The maximum number of distributions that you want CloudFront to return in the response body. The maximum and default values are both 100.
