cacheControl property
CacheControl is the Cache-Control policy the edge serves this site's HTML under — how long a reader may hold a stale page before asking again. Assets are content-addressed and are not governed by it.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? cacheControl;
