CacheValidationPolicy

Server cache validation policy. Specifies when server-side cache entries are validated.

With expiration-based validation, source materials and vignettes are periodically checked to see whether they have changed. With catalog-based validation, source images are checked only after the catalog::TimeStamp value changed.

Catalog-based validation is recommended when both material and vignette catalogs are used. Expiration-based validation should be used when vignettes are referenced in Image Rendering requests directly by path.

Properties

Enum. 0 to select expiration-based validation. 1 to select catalog-based cache validation.

Default

Inherited from default::CacheValidationPolicy if not defined or if empty.
